Long wearing solid carbide insert knives 14x14x2mm-30° are offered for spiral helical cutter block head, moulder head, shaper, rebate cutterhead and other woodworking applications.-Inexpensive carbide cutter can be rotated or replaced in a few minutes when it gets dull or chipped, no need to shut down machine for a long time like straight HSS planer knife .There are 14 tolerance classes that control the indexability of the inserts. Each class is denoted by a capital letter. Letters for tolerances are A, B, C, D, E, F, G, H, J, K, L, M, U and N.
According to ANSI B212.4-2002 standard, identification of the indexable insert includes 10 positions denoted by a capital letter. Each position (from 1 to 10) defines a characteristic of the insert in the following order:
The mathematical expression denoting one of several parameters that describe surface texture (same as average roughness Ra). Average roughness is the arithmetic average height deviation of the measured surface profile from the profile centerline. See surface texture.The seventh position indicates the cutting point configuration: a radius or a facet. In the case of a radius, the number indicates how many of 1 ⁄ 64 of an inch in the radius: 0 – sharp corner (0.002″ max. radius); 0.2 – 0.004″; 0.5 – 0.008″; 1 – 1 ⁄ 64″; 2 – 1 ⁄ 32″; 3 – 3 ⁄ 64″; 4 – 1 ⁄ 16″; 5 – 5 ⁄ 64″; 6 – 3 ⁄ 32″; 7 – 7 ⁄ 64″; 8 – 1 ⁄ 8″; 10 – 5 ⁄ 32″; 12 – 3 ⁄ 16″ 14 – 7 ⁄ 32″ = 14; 16 – 1 ⁄ 4″; X – Any other corner radius.
American National Standard ANSI B212.4-2002 covers the identification system for indexable-type inserts for both single-point and multiple-point cutting tools. It was published on October 29, 2002. The earlier editions of the standard are:
For all other polygons, dimension B is the distance, measured along the bisector of the rounded off corner angle and a gage roll of nominal I.C. size tangent to the two sides opposite the corner (Figure 2). For example, if a tolerance letter is H, tolerances on dimensions (± from nominal) are: 0.0005″ on dimension A, 0.0005″ on dimension B and 0.001″ on dimension T.Due to the magazine’s space limitations, the authors provide the following tables showing most popular Kennametal’s indexable inserts only for general turning of steel, cast iron, and nonferrous alloys. These tables don’t cover all Kennametal chip breakers. (Figure 4 and Figure 5 also show Kennametal Inc. insert identification system and chip breaker identification system respectively.)
Tolerances on dimensions (± from nominal) are denoted by letters A, B and T. Dimension A is the nominal inscribed circle (I.C.) of the insert. Dimension T is the thickness of the insert. For pentagon, triangle and trigon shapes, dimension B is the insert height, i.e., the distance between one side and the opposite corner (Figure 2).Nine relief angle values have been described in ANSI B212.12-1991 standard. These angles are the difference from 90° measured in a plane normal to the cutting edge generated by the angle between the flank and top surface of the insert. Each relief angle is denoted by a capital letter as follows:
Inserts selection depends on workpiece material, chip control, surface finish, tool life, and the machine tool’s power and torque requirements. One of the commonly used indexable inserts for general turning is CNMG 432.
Imaginary circle that touches all sides of an insert. Used to establish size. Measurements are in fractions of an inch and describe the diameter of the circle.
What are the types of carbide inserts?
Insert coatings To increase the life of carbide tools, they are sometimes coated. Five such coatings are TiN (titanium nitride), TiC (titanium carbide), Ti(C)N (titanium carbide-nitride), TiAlN (titanium aluminium nitride) and AlTiN (aluminium titanium nitride).
Conditioning of the cutting edge, such as a honing or chamfering, to make it stronger and less susceptible to chipping. A chamfer is a bevel on the tool’s cutting edge; the angle is measured from the cutting face downward and generally varies from 25° to 45°. Honing is the process of rounding or blunting the cutting edge with abrasives, either manually or mechanically.In case of a facet, two letters are used. The first letter designates the facet angle: A – 45°; D – 60°; E – 75°; G – 87°; P – 90°; Z – Any other facet angle. The second letter designates the facet clearance angle:

This position designates the number of eighths of an inch in the nominal size of the I.C. It will be a one-digit number when the number of eighths of an inch in the I.C. is a whole number: 1 – 1 ⁄ 8″; 2 – 1 ⁄ 4″; 3 – 3 ⁄ 8″; 4 – 1 ⁄ 2″; 5 – 5 ⁄ 8″; 6 – 3 ⁄ 4″; 7 – 7 ⁄ 8″;
Replaceable tool that clamps into a tool body, drill, mill or other cutter body designed to accommodate inserts. Most inserts are made of cemented carbide. Often they are coated with a hard material. Other insert materials are ceramic, cermet, polycrystalline cubic boron nitride and polycrystalline diamond. The insert is used until dull, then indexed, or turned, to expose a fresh cutting edge. When the entire insert is dull, it is usually discarded. Some inserts can be resharpened.
The fourth position is a capital letter denoting differences in design of insert, such as the existence of fixing holes, countersinks and special features on rake surfaces. There are 15 standard types in design as follows (Figure 3):The sixth position is a significant one- or two-digit number indicating the number of sixteenths of an inch in the thickness of the insert. It is a one-digit number when the number of sixteenths of an inch in the thickness is a whole number: 1 – 1 ⁄ 16″; 2 – 1 ⁄ 8″; 3 – 3 ⁄ 16″; 4 – 1 ⁄ 4″; 5 – 5 ⁄ 16″; 6 – 3 ⁄ 8″; 7 – 7 ⁄ 16″; 8 – 1 ⁄ 2″; 9 – 9 ⁄ 16″; 10 – 5 ⁄ 8″. Any machining process used to part metal or other material or give a workpiece a new configuration. Conventionally applies to machining operations in which a cutting tool mechanically removes material in the form of chips; applies to any process in which metal or material is removed to create new shapes. See metalforming. On rectangular and parallelogram inserts, the width and length dimensions are used in place of the I.C. A two-digit number designates the sizes of these inserts. The first digit indicates the number of eighths of an inch in the width and the second digit indicates the number of fourths of an inch in the length of the insert.Space provided behind the cutting edges to prevent rubbing. Sometimes called primary relief. Secondary relief provides additional space behind primary relief. Relief on end teeth is axial relief; relief on side teeth is peripheral relief.
What are the grades of carbide inserts?
Insert grades with Inveio®GC4425 – the first choice grade for steel turning … GC4415 – your option for steel turning with high metal removal rates. … GC4305 – steel turning efficiency in stable conditions. … GC4335 – steel turning efficiency in unstable conditions. … GC2220 – stainless steel turning in stable conditions
Angle of inclination between the face of the cutting tool and the workpiece. If the face of the tool lies in a plane through the axis of the workpiece, the tool is said to have a neutral, or zero, rake. If the inclination of the tool face makes the cutting edge more acute than when the rake angle is zero, the rake is positive. If the inclination of the tool face makes the cutting edge less acute or more blunt than when the rake angle is zero, the rake is negative.Workpiece is held in a chuck, mounted on a face plate or secured between centers and rotated while a cutting tool, normally a single-point tool, is fed into it along its periphery or across its end or face. Takes the form of straight turning (cutting along the periphery of the workpiece); taper turning (creating a taper); step turning (turning different-size diameters on the same work); chamfering (beveling an edge or shoulder); facing (cutting on an end); turning threads (usually external but can be internal); roughing (high-volume metal removal); and finishing (final light cuts). Performed on lathes, turning centers, chucking machines, automatic screw machines and similar machines.
The 10th position is only used if there are letters in the seventh position. It will be a significant number representing the nominal sixty-fourths of an inch in length of the primary facet: 1 – 1 ⁄ 64″; 2 – 1 ⁄ 32″; 3 – 3 ⁄ 64″; 4 – 1 ⁄ 16″; 5 – 5 ⁄ 64″; 6 – 3 ⁄ 32″; 7 – 7 ⁄ 64″; 8 – 1 ⁄ 8″; 9 – 9 ⁄ 64″; 10 – 5 ⁄ 32″.
Solid carbide insert knives 14x14x2mm-30° can be used on Grizzly Tools, Carbatec, Craftex CX series, Shopfox , King Canada jointer and planer machne with spiral cutter block head after June 1st 2015 and other woodworking applications.Carbide inserts are used at high speeds that enable faster machining, ultimately resulting in better finishing. Choosing a correct carbide insert is vital because it can risk damaging the insets, machine, and cutting product.
In the medical profession, doctors and surgeons rely on accurate and durable tools for all kinds of medical procedures and insert carbides are one of them.
The industry of cutting tools has expanded ten-fold in the last few years. Among hundreds of options, it is hard to choose the right tool. Selecting a tool that can produce low cutting forces with a good surface finish and the smooth cutting action is complex.
Milling aluminum requires C2 carbide grade inserts for rough and C3 grade for finishing. Only general grade carbide inserts grades with a medium grain with excellent wear resistance for roughing and finishing applications where sharp edges are required.
Turning is an almost flawless process for ceramics. In general, it is a continuous machining mechanism that allows a single carbide insert to be engaged in the cut for a longer time. This is an excellent tool to generate the high temperatures that make ceramic inserts perform optimally.Carbide inserts are used in making different materials like steel alloys. These steel alloys are becoming harder in many applications. This steel hardens to 63 RC are commonly used in the dye and mold industry.
What size carbides do I need?
Carbide Length also is a very important consideration. If you are a trail rider running 96 or fewer studs, we recommend you go with a 4.5-6” carbide. If you run more than 96 studs, we suggest going with an 8-9” carbide. If you are a mountain/powder rider, a shorter 4-6” carbide will suffice.
Most of the machining performance on molds and dies focuses on common mold materials in the milling industry. Only top form geometrics are different from one another. Here are some mold materials that are preferable in the milling industry ,Below is HUANA Milling Inserts Order number and introductionFor instance, aerospace machining uses carbide inserts. They used round carbide inserts when they want to machine hard steels. This is how profile provides a more robust tool without vulnerable sharp corners.
This article is for you if you want to know how to choose the correct carbide inserts. Here you’ll get to know everything about the proper carbide inserts for your cutting applications.Heat resistant super alloys (HRSAs) are extensively used in the aerospace industry and gain acceptance in the medical, automobile, power generation, and semiconductor industries. Heat resistant super alloys like Waspalloy and titanium 6Al4V are joined with titanium, magnesium, and aluminum matrix that altogether possess machining challenges.
Carbide inserts, mainly tungsten and cobalt, start in powder form. Then in the mill, the dry raw material is mixed with a combination of ethanol and water. This mixture results in a gray slurry solution with a consistency like a yogurt drink. This mixture is dried and then sent to a laboratory for a quality check. This powder comprises agglomerates, small balls of 20 to 200 microns diameter, and then transported to pressing machines where inserts are made with different grades.To machine sintered metals, inserts’ choice depends upon the material and workpiece. Carbide inserts having positive rake geometrics can effectively cut thin-wall sintered metals stock. However, thick-walled sintered metal parts need ceramic inserts with negative cutting edge geometry that provide smooth flat surface area to the workpiece.
Some specially formulated high-temperature grades withstand the heat generation when steel hardens to 60 RC. On the other hand, shock-resistant carbide inserts with an aluminum oxide coating counter the high temperatures generated by milling hard steels.
On the other hand, Milling can be compared to interrupted machining in turning. Each carbide insert on the tool body is in and out of the cut during each cutter revolution. If compared to turning, hard Milling needs much higher spindle speeds to achieve the same surface speed
Carbide inserts are tools used to accurately machine metals, including steels, carbon, cast iron, high-temperature alloys, and other non-ferrous metals. These are replaceable and come in various styles, grades, and sizes.
To meet the surface speed of a turning mechanism on a three-inch diameter workpiece, a three-inch diameter milling cutter with four teeth must run four times the turning speed. With ceramics, the object generates a threshold of Heat per insert. Therefore, each insert must travel faster to generate a single point turning tool’s heat equivalent in milling operations.Due to advancements in technology, powder metallurgy produces extra hard sintered metals for various industries. For such industries, a powdered nickel composite alloy is made by combining tungsten and titanium carbide to achieve hardness from 53 to 60 RC.Using advanced technology, the cutting surface of an insert is given a round, oval, or any other geometrical shape. Significant benefits in insert life and stability have been seen with emerging technology. It is safe to say that future technological advances will drive further development in the field, and even more substantial achievements will occur.Tungsten carbide inserts are also used in the nuclear science industry as effective neutron reflectors. This material was also used during early investigations in nuclear chain reactions, especially for weapons protection. In recent times, aluminum manufacturers have developed better high-strength materials with hardness characteristics ranging from 157 to 167 Brinell. It is hard to machine very smooth surfaces on aluminum, so polishing becomes a critical operation in the final process. To engage the surface speed of a turning mechanism on a three-inch diameter workpiece, a three-inch diameter milling cutter with three teeth must run with a minimum of four times the turning rate. With ceramics, the object generates a potential of Heat for each carbide insert. Therefore, in milling operations, each carbide insert must travel faster to generate a single point turning tool’s heat equivalent.Carbide inserts with unique geometries and coatings withstand mechanical shock and Heat while resisting abrasive wear. However, using these inserts productively can require various external factors—one of which may be a partnership with a knowledgeable tool supplier.
Choosing the right carbide insert is not an easy task, but if you keep all the mentioned parameters in mind, this process can be easy and convenient. Don’t hang with the insert’s brand image because it will not affect its performance. Always choose a carbide insert according to your use, whether for Milling, threading, or any other industry.Carbide inserts are also used in the threading industry. High-quality lay-down triangular carbide inserts provide a solution for most threading industry needs. These carbide inserts manage a wide range of applications, from essential to complex ones. The carbide particles and the nickel alloy matrix reach up to 90 RC. When milling such materials, the carbide inserts coated with different materials suffer rapid flank wear with flat primary cutting edges. However, the extra hard particles within the insert create ‘microchatter’ that speeds up the insert wear. It would help if you were careful because sometimes carbide inserts also fracture under the sheer pressure of machining the hard shock. To match a threading operation’s surface speed on a three-inch diameter workpiece, a three-inch diameter threading cutter with four teeth must run four times the turning speed. With ceramics, the object generates a threshold of Heat per insert. Therefore, in threading operations, each insert must travel faster to generate a single point turning tool’s heat equivalent.Like other industries, carbide inserts are also used in the milling industry. They solve every conceivable application problem. These carbide inserts include ball nose carbide inserts, high feed carbide inserts, toroid carbide inserts, backdraft carbide inserts, and flat bottom carbide inserts. All these carbide inserts solve specific problems in the milling industry.
How do I choose insert size?
How to choose insert sizeDetermine the largest depth of cut, apDetermine the necessary cutting length, LE, while also considering the entering (lead) angle of the tool holder, the depth of cut, ap and the machine specification.
Mainly people consider macro geometry and carbides’ physical shape when the role of geometry is discussed. Here, microgeometry is equally essential that deals with the microscopic form’s cutting edge.
How do you identify carbide?
And this one’s much heavier. Now if you can’t determine from that test the next test we do is simply the magnet. Test steel is very attracted to the magnet.
Carbide inserts, mainly tungsten and cobalt, start in powder form. Then in the mill, the dry raw material is mixed with a combination of ethanol and water. This mixture results in a gray slurry solution with a consistency like a yogurt drink. This mixture is dried and then sent to a laboratory for a quality check. This powder comprises agglomerates, small balls of 20 to 200 microns diameter, and then transported to pressing machines where inserts are made.
There are some primary considerations on how to choose the correct carbide inserts. One of those is the cutting operation, whether turning, Milling, or drilling. Carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a more enormous tipped tool whose shank is made of another material, usually carbon tool steel. This benefits from using carbide at the cutting interface without the high cost and brittleness of making the complete tool out of carbide. Most modern face mills use carbide inserts and many lathe tools and endmills.
Carbide inserts geometry can be divided into three basic styles optimized for several operations, including roughing, finishing, and medium. Here are some diagrams that will explain each geometrical shape’s working area, based on geometrical chip breaking with the depth of cut.A dog bone carbide insert is a two-edged insert with a narrow mounting center and also offers a broader cutting feature at both ends. This type of carbide insert is used for grooving. It’s tips included angles that can be 35, 50, 55, 60, 75, 80, 85, 90, 108, 120, and 135 degrees.
Triangle or Trigon carbide inserts have a triangular shape with three equal sides and three tips with angles of 60 degrees. They are three-cornered inserts that resemble a triangle but with a modified form like bowed sides or medium-sized angles that include grades at the tips.Keeping an eye on grades is also essential when choosing carbide inserts. Always consider toughened grades because they provide edge security against the high radial cutting forces. They also offer severe entry and exist shocks when encountered in harden sheets.
The entering angle, KAPR (or lead angle, PISR), is the angle between the cutting edge and the feed direction. It is essential to choose the correct entering/lead angle for a successful turning operation. The entering/lead angle influences:
According to their shape and material used, several different types of carbide inserts are used for various purposes. These inserts are replaceable attachments for cutting tools that typically consist of the actual cutting edge. These carbide inserts include:Beryllium Copper is also the preferred mold material in the milling industry for some segments. These metal removal rates are also as high as eight to ten times faster than machining steel. Their hardness level ranges from 10 RC to 40 RC, which is nearly double that of aluminum.
The geometry of an insert is an essential aspect because it deals with the shape of chip control. Different shapes and angles provide optimal results in breaking chips, depending upon their material and application.
These alloys are super hard, and they need higher cutting zone temperatures greater than 2,000°F. If we talk about carbide inserts used to cut these alloys, these are even super hard.
What are round carbide inserts used for?
Carbide inserts are tools used to accurately machine metals, including steels, carbon, cast iron, high-temperature alloys, and other non-ferrous metals. These are replaceable and come in various styles, grades, and sizes.
Four-sided carbide inserts include diamond, rhombic, square, and rectangle shapes. Diamond-shaped carbide inserts are four-sided with two acute angles used for material removal. The medical industry is the most common industry for the use of carbides. However, the base of the tool itself is crafted with titanium or stainless steel, and the tip of the tool is made of tungsten carbide. The nose radius, RE, is a crucial factor in carbide inserts operations. Carbide Inserts are available in different sizes of nose radius. The selection depends on the depth of cut and feed and influences the surface finish, chip breaking, and insert strength.
Carbide inserts are widely used in the jewelry-making industry. They are used for both jewelry shaping and in the jewelry itself. Tungsten material falls behind the diamond on the hardness scale, and it is an excellent material used in making wedding rings and other jewelry pieces.
The tools cutting industry has drastically changed, and these changes can be seen in inserts for Milling and turning the inappropriate materials. This section highlights that how carbide inserts change the inappropriate materials.Turning is an almost flawless operation for ceramics. Commonly, it is a continuous machining process that allows a single insert to be engaged in the cut for relatively long periods. This is an excellent tool to generate the high temperatures that make ceramic inserts perform optimally.
Inserts are made of several different materials but commonly constructed of carbide, micro-grain carbide, ceramic, CBN, cermet, diamond PCD, cobalt, silicon nitride, and high-speed steel. The coating over the insert increases the wear resistance and life span of this cutting tool. These coatings include titanium nitride, titanium carbonitride, titanium aluminum nitride, aluminum titanium nitride, aluminum oxide, chromium nitride, zirconium nitride, and diamond DLC.
Aluminum is the preferred mold material in the milling industry for some segments. These metal removal rates are as high as eight to ten times faster than machining steel.People have been using carbide inserts since the late 1920s. These cutting tools are ubiquitous in the metal cutting world. Here are some of the carbide insert’s applications in the metal cutting industry. Carbides are extremely helpful for dozens of business owners, construction workers, and many other industries worldwide. On the other hand, Milling can be compared to an interrupted mechanism in turning. Each carbide insert on the tool body is in and out of the cut when each cutter revolves. Compared to turning, hard Milling needs much higher spindle speeds to achieve the same surface speed for efficient working. To machine Heat resistant super alloys (HRSAs), inserts’ choice depends upon the material and workpiece. Carbide inserts having positive rake geometrics can cut thin wall Heat resistant super alloys (HRSAs) stock effectively. However, thick-walled alloy parts need ceramic inserts with negative cutting edge geometry that provide smooth surface area to the workpiece. Square-shaped carbide inserts have four equal sides. On the other hand, Rectangular carbide inserts have four sides. Two of the sides are longer than the other two. These types of carbide inserts are used for grooving purposes where the short sides of inserts have the actual cutting edge. A ball nose mill carbide insert has a ‘hemispheric’ ball nose whose radius is half than the cutter diameter. This carbide insert helps machine female semicircles, grooves, or radii.Mold makers used to cut the parts before heat treating but now precision machining tools are used in the fully hardened condition to avoid any heat treating distortion. With this technique, even fully hardened materials can be machined economically with the carbide inserts.
How do I know what size carbide insert to use?
Make sure that you choose your carbide insert size according to the particular machining requirements and the availability of cutting tools in your position. The size of the inserts should be as large as possible for greater stability. Carbide inserts of IC 25mm or greater are required for heavy machining operations.

Mining and tunneling cutting tools are most often fitted with cemented carbide tips, the so-called “button bits”. Artificial diamond can replace the cemented carbide buttons only when conditions are ideal, but as rock drilling is a tough job cemented carbide button bits remain the most used type throughout the world. Although the marketing pitch was slightly hyperbolic (carbides being not entirely equal to diamond), carbide tooling offered an improvement in cutting speeds and feeds so remarkable that, like high-speed steel had done two decades earlier, it forced machine tool designers to rethink every aspect of existing designs, with an eye toward yet more rigidity and yet better spindle bearings.Regarding fine-grained hardmetal, an attempt has been made to follow the scientific and technological steps associated with its production; this task is not easy, though, because of the restrictions placed by commercial, and in some cases research, organisations, in not publicising relevant information until long after the date of the initial work. Thus, placing data in an historical, chronological order is somewhat difficult. However, it has been possible to establish that as far back as 1929, approximately 6 years after the first patent was granted, Krupp/Osram workers had identified the positive aspects of tungsten carbide grain refinement. By 1939, they had also discovered the beneficial effects of adding a small amount of vanadium and tantalum carbide. This effectively controlled discontinuous grain growth. The plates of this superhard composite are applied to manufacturing of metal-cutting and drilling tools; they are usually soldered on the cutting tool tips. Heat post-treatment is not required. The pobedit inserts at the tips of drill bits are still very widespread in Russia. Uncoated tips brazed to their shanks were the first form. Clamped indexable inserts and today’s wide variety of coatings are advances made in the decades since. With every passing decade, the use of carbide has become less “special” and more ubiquitous.
The initial development of cemented and sintered carbides occurred in Germany in the 1920s. ThyssenKrupp says [in historical present tense], “Sintered tungsten carbide was developed by the ‘Osram study society for electrical lighting’ to replace diamonds as a material for machining metal. Not having the equipment to exploit this material on an industrial scale, Osram sells the license to Krupp at the end of 1925. In 1926 Krupp brings sintered carbide onto the market under the name WIDIA (acronym for WIe DIAmant = like diamond).” /ˈviːdiə/ Machinery’s Handbook gives the date of carbide tools’ commercial introduction as 1927. Burghardt and Axelrod give the date of their commercial introduction in the United States as 1928. Subsequent development occurred in various countries.During World War II there was a tungsten shortage in Germany. It was found that tungsten in carbide cuts metal more efficiently than tungsten in high-speed steel, so to economise on the use of tungsten, carbides were used for metal cutting as much as possible.
Why is carbide so expensive?
Compared with other metals, carbide is very expensive because it contains cobalt, which is severely short and has very high demand in various fields such as batteries for smartphones, or other electrical appliances. That is why the price of cobalt is increasing, which also makes carbide price increase.
Carbide is more expensive per unit than other typical tool materials, and it is more brittle, making it susceptible to chipping and breaking. To offset these problems, the carbide cutting tip itself is often in the form of a small insert for a larger tipped tool whose shank is made of another material, usually carbon tool steel. This gives the benefit of using carbide at the cutting interface without the high cost and brittleness of making the entire tool out of carbide. Most modern face mills use carbide inserts, as well as many lathe tools and endmills. In recent decades, though, solid-carbide endmills have also become more commonly used, wherever the application’s characteristics make the pros (such as shorter cycle times) outweigh the cons (mentioned above). As well, modern turning (lathe) tooling may use a carbide insert on a carbide tool such as a boring bar, which are more rigid than steel insert holders and therefor less prone to vibration, which is of particular importance with boring or threading bars that may need to reach into a part to a depth many times the tool diameter.Cemented carbides are metal matrix composites where carbide particles act as the aggregate and a metallic binder serves as the matrix (analogous to concrete, where a gravel aggregate is suspended in a cement matrix). The structure of cemented carbide is conceptually similar to that of a grinding wheel, but the abrasive particles are much smaller; macroscopically, the material of a carbide cutter appears homogeneous.
How is size of insert measured by ANSI?
A two-digit number designates the sizes of these inserts. The first digit indicates the number of eighths of an inch in the width and the second digit indicates the number of fourths of an inch in the length of the insert.
Cemented carbides are a class of hard materials used extensively for cutting tools, as well as in other industrial applications. It consists of fine particles of carbide cemented into a composite by a binder metal. Cemented carbides commonly use tungsten carbide (WC), titanium carbide (TiC), or tantalum carbide (TaC) as the aggregate. Mentions of “carbide” or “tungsten carbide” in industrial contexts usually refer to these cemented composites.
The Widia [de] name became a genericized trademark in various countries and languages, including English (widia, /ˈwɪdiə/), although the genericized sense was never especially widespread in English (“carbide” is the normal generic term). Since 2009, the name has been revived as a brand name by Kennametal, and the brand subsumes numerous popular brands of cutting tools. The first cemented carbide developed was tungsten carbide (introduced in 1927) which uses tungsten carbide particles held together by a cobalt metal binder. Since then, other cemented carbides have been developed, such as titanium carbide, which is better suited for cutting steel, and tantalum carbide, which is tougher than tungsten carbide. The coefficient of thermal expansion of cemented tungsten carbide is found to vary with the amount of cobalt used as a metal binder. For 5.9% cobalt samples, a coefficient of 4.4 µm·m·K was measured, whereas 13% cobalt samples have a coefficient of around 5.0 µm·m·K. Both values are only valid from 20 °C (68 °F) to 60 °C (140 °F) due to non-linearity in the thermal expansion process.
How do I identify my cutting inserts?
Carbide turning inserts, like all other metal cutting tools, are identified with a series of letters and numbers. These refer to the Turning Tool ISO code system that provides a (relatively) simple way to identify carbide inserts.
Pobedit is usually produced by powder metallurgy in the form of plates of different shapes and sizes. The manufacturing process is as follows: a fine powder of tungsten carbide (or other refractory carbide) and a fine powder of binder material such as cobalt or nickel both get intermixed and then pressed into the appropriate forms. Pressed plates are sintered at a temperature close to the melting point of the binder metal, which yields a very tight and solid substance.Pobedit (Russian: победи́т) is a sintered carbide alloy of about 90% tungsten carbide as a hard phase, and about 10% cobalt (Co) as a binder phase, with a small amount of additional carbon. It was developed in the Soviet Union in 1929, it is described as a material from which cutting tools are made. Later a number of similar alloys based on tungsten and cobalt were developed, and the name of ‘pobedit’ was retained for them as well.Most of the time, carbide cutters will leave a better surface finish on a part and allow for faster machining than high-speed steel or other tool steels. Carbide tools can withstand higher temperatures at the cutter-workpiece interface than standard high-speed steel tools (which is a principal reason enabling the faster machining). Carbide is usually superior for the cutting of tough materials such as carbon steel or stainless steel, as well as in situations where other cutting tools would wear away faster, such as high-quantity production runs. In situations where carbide tooling is not required, high-speed steel is preferred for its lower cost.
What was considered ‘fine’ in one decade was considered not so fine in the next. Thus, a grain size in the range 0.5–3.0 μm was considered fine in the early years, but by the 1990s, the era of the nano-crystalline material had arrived, with a grain size of 20–50 nm.
Tungsten carbide has become a popular material in the bridal jewellery industry, due to its extreme hardness and high resistance to scratching. Given its brittleness, it is prone to chip, crack, or shatter in jewellery applications. Once fractured, it cannot be repaired.Since the mid-1960s, steel mills around the world have applied cemented carbide to the rolls of their rolling mills for both hot and cold rolling of tubes, bars, and flats. Every carbide insert has an identification code attached to it. This isn’t a random collection of letters and numbers, but a comprehensive system that can help you identify the correct tool. R.D. Barrett was established in 1975 by Ron Derek Barrett, an ex employee of both DS & G Lathes and Ford Motor Company. We hold one of the UK largest stock of engineering tooling.
There are ten different insert shapes, but it’s quite a loose classification. There are variations within the classification system which means they should be taken as an identifier.
By understanding the Turing Tool ISO system, you can quickly identify carbide inserts. Let’s look in a little more detail at each part of the coding system.Carbide inserts are used to accurately machine metals, including steels, carbon, cast iron, high-temperature alloys and other non-ferrous metals. Carbide inserts are replaceable and indexable and come in a huge variety of styles, sizes and grades.
The sheer variety of carbide inserts available and their precision use means that there needed to be a simple system devised to categorise them. Carbide turning inserts, like all other metal cutting tools, are identified with a series of letters and numbers. These refer to the Turning Tool ISO code system that provides a (relatively) simple way to identify carbide inserts. In this article, we describe what the Turning Tool ISO code system is and how you can use it to identify your carbide inserts.
This code is used to describe the style of turning tool. There are 14 different holder styles, with each differentiated by the approach angle of the tool.
Every carbide insert can be identified using the Turning Tool ISO code system. This straightforward shorthand system covers everything you need to know, and need to tell us, when ordering your new carbide insert.
At R.D. Barrett, we hold the UK’s largest selection of professional turning tools, including carbide inserts. We have a huge range of carbide inserts suitable for all applications in various sizes, shapes and grades.
The ISO code is based on the metric system, with measurements made in millimetres. In America, they use a different system called the American National Standard ANSI B212.4-2002 system that uses inches. We don’t cover that in this guide.The ninth and final part of the Turning Tool ISO code is the length of the cutting insert. The figure is measured in mm, so a 10 would mean the cutting insert has a 10mm cutting edge length. There are five different types of clamping methods used for tuning tools. The various methods describe how the carbide insert is clamped, the tool’s shape and the force and rigidity of clamping. The system provides a universal framework for identifying the carbide insert that you are using, or need to purchase. If you know the identification code, selecting a replacement part is simple and straightforward.Knowing the length of the holder is essential in selecting the right carbide insert. Each letter refers to a different length. While the differences may seem small, selecting the right part – or a suitable part if your chosen length isn’t available to use – is crucial.
Carbide inserts can be used at high speeds, which enables faster machining, which results in better finishes. It’s crucial that you select the correct carbide insert for the material that you are cutting or you could risk damaging the insert, the machine and the workpiece.
If you know the identification code of your insert, we can provide a replacement for you. Even if you don’t have all the information to hand, we can use our expert knowledge gained from over 45 years in business to help you to narrow down your choice of tool.
