What Exactly Are Carbide Inserts?
Carbide inserts are used to manufacture metals such as steels, carbon, cast iron, high-temperature alloys, and other non-ferrous metals precisely. Carbide inserts are removable and indexable, and they are available in a wide range of designs, sizes, and grades.
Carbide inserts may be utilized at high speeds, allowing for quicker machining and superior finishes. It is critical that you use the suitable carbide insert for the material being cut, otherwise you risk harming the insert, the machine, and the workpiece.
How Can You Identify Carbide Inserts?
Using the Turning Tool ISO code system, each carbide insert can be recognized. This simple abbreviation scheme covers everything you need to know and tell us when buying your new carbide insert. The ISO code is based on the metric system, with millimeter measures. This is how it works.
Every carbide implant is labelled with an identifying number. This is not a random collection of letters and numbers, but rather a thorough system that may assist you in locating the appropriate tool. Each letter or number in the identifying code corresponds to one of the sentences listed below..
- Clamping Method of Insert
- Insert Shape
- Holder Style
- Clearance Angle of Insert
- Hand of Tool Holder
- Height of Shank
- Width of Shank
- Length of Holder
- Length of Insert Cutting Edge
Each component has an effect on the coding procedure, which ultimately facilitates straightforward determination of the carbide insert. As soon as you have a firm grasp of the Turing Tool ISO system, you will have no trouble selecting the appropriate carbide insert. The system gives you access to a universal framework that you may use to determine the specific carbide insert that you are using or that you wish to acquire. If you are familiar with the particular identifying code, choosing the appropriate carbide insert will be a piece of cake.
- Clamping Method Of Insert Five distinct approaches to clamping may be used while tuning instruments. The several techniques explain how the carbide insert is secured, as well as the geometry of the tool, the amount of force used, and the stiffness of the clamping.
- Insert Shape There are 10 distinct insert forms available; however, the categorization is not very strict. Because there are differences within the categorization system, they should be treated as identifiers because they serve that purpose.
- Holder Style This code is used to define the manner in which the turning tool is constructed. There are 14 distinct designs of holders, and the approach angle of the tool is what differentiates each one from the others.
- The Angle Of Clearance For The Insert The fourth letter in the phrase specifies the clearance angle of the insert. There is a range of seven possible clearance angles, starting at 0 degrees and going up to 25 degrees.
- Tool Holder Hand It is also important to be aware of the orientation of the instrument, namely whether it is right-handed, left-handed, or neutral (centered).
- Shank Holder The height of the shank is the topic of discussion for the sixth code. For instance, if the sixth number is 20, this would indicate that the shank is 20 millimeters in height.
- Shank Width The total width of the shank, which is equivalent to the width discussed before. Again, if the number is 20, the width of the shank would be 20 millimeters.
- Holder Length When choosing the appropriate carbide insert, it is important to be familiar with the length of the holder. There are a variety of lengths represented by each letter. Although the variations may not seem to be significant at first glance, it is very important to choose the appropriate component (or a compatible component in the event that your preferred length is not available to use).
- Insert Cutting Edge Length The length of the cutting insert is the ninth and last component of the Turning Tool ISO code. Since millimeters are the unit of measurement, a value of 10 indicates that the cutting insert has a cutting edge length of 10 millimeters.
How to choose the best Suitable Insert
- Types of Carbide Inserts
Carbide inserts are available in a wide range, each of which is suited for a certain use case.
The following are some of the most common types:
- Turning carbide inserts
- Threading carbide inserts
- Grooving carbide inserts
- Milling carbide inserts
- Drilling carbide inserts
- Boring carbide inserts
The Most Important Considerations to Make When Choosing the Appropriate Inserts
There are a number of characteristics that need to be taken into consideration while selecting the appropriate carbide inserts. In the end, such criteria influence whether or not you will achieve high machining performance as well as chip control in order to provide ideal outcomes.
The following are the most important considerations to keep in mind:
- The Geometry of the Inserts
On the basis of their way of functioning, geometries may be classified into one of three basic styles. These fashions include the following:
- Roughingis characterized by a combination of a high depth of cut and feed rate, and it is used primarily for processes that need the greatest level of edge security.
- Mediumis an excellent choice for medium-level work up to mild roughing. Both the feed rate and the variety of cut depth combinations are available.
- Finishingis an operation that may be performed with light depths of cut and very modest input rates. Suitable for tasks that need minimal amounts of cutting power.
- Insert Grade
The insert grade is calculated in the first place, almost often on the basis of the following:
- Component material
- Procedure should be followed (Finishing, medium, roughing)
- The circumstances of the machining, rated as either favorable, moderate, or challenging.
- Both the tool geometry and the grade are complementary from a technical standpoint.
For example, the toughness of a grade may be able to compensate for the absence of strength in the geometry of a carbide insert.
- Insert Shape
It is crucial to make sure that the carbide shape you choose is a reasonably necessary tool entry angle accessibility before you make your choice. Always give careful consideration to selecting the nose angle that offers the greatest possible implantation and dependability. Having said so, this aspect has to be weighed against the requirement for cuts variation to be carried out. In an ideal situation, a big nose angle is robust, but it demands a greater amount of machine power. In addition to this, it has a greater propensity to vibrate. On the other hand, a nose angle that is not too steep is considered to be somewhat weak and has a limited amount of cutting edge interaction. As a result, it has a greater propensity to be more sensitive to the many consequences that heat may have.
- Insert Size
Always choose a carbide insert size based on the precise requirements of the application as well as the available area for cutting tools in the application. A size of insert that is quite big gives more stability. Carbide inserts with a size greater than IC 25 millimeters are required for heavy-duty machining. Always take into consideration the maximum depth of cut while selecting the appropriate size of carbide insert. When selecting the tool holder entering tool, the depth of cut, and the machine specification, cutting length should be taken into consideration.
- Material That Is Going To Be Machined
Carbide inserts are used in the machining process for a variety of different materials. Therefore, you need to make sure that you choose the appropriate tool that is suited for the particular material.
The following items are examples of some of these materials:
- Aluminum
- Bronze
- Hardened tool steel
- Soft tool steel
- Stainless steel
- Iron Castings
- Metals that do not include iron
- Alloy that is resistant to heat Titanium alloy
- Materials with a high degree of rigidity
- Machine Tool Type
There is a great deal of variability in the machine tools that are utilized with carbide inserts.
Conventional vertical machining centers, Swiss-type lathes, CNC lathes, 5 axes, turning machines, lathe machines, and 5 axis turning machines are among the most popular types.
- Insert Materials
These carbide inserts include design configurations that include a body with interchangeable cutting components; as a result, they are referred to as indexable inserts. In most cases, the material of the tool has to be tougher than the material of the workpiece before it can be used on the workpiece. It is of the utmost importance to make certain that the material can bear heat and mechanical stresses in addition to oxidation. In addition, the materials used in the tool must be able to withstand the required levels of heat and oxidation, as well as have enough levels of strength and hardness. It is helpful in ensuring that the tool life is appropriate within the requirements that are necessary. Therefore, it is essential to take into consideration the particular use before deciding on the most suitable material for the tool. Carbide is the primary component used throughout the production process of carbide inserts. On the other hand, there are many other tool material groups that may be employed to produce a range of carbide inserts.
Some of these materials include the following:
- Cemented carbide
- High-speed steel (HSS)
- Cermet
- Ceramics
- Silicon nitride
- Cubic boron nitride
- Polycrystalline diamond (PCD)
The main types of cemented carbide used to manufacture inserts include tungsten, titanium carbide. Each group features different types, commonly known as tool material grades or simply grades, tantalum carbide, and tungsten carbide.

- Conventional inserts: Milling inserts AMPT1135 1604, RPMT1204
Milling inserts with the part numbers AMPT1135 1604, and RPMT1204 are often used in indexable square shoulder end milling cutters and face milling cutters. They are designed to be used in the processing of stainless steel.
APMT inserts are specialized cutting tools that only have one side and are outfitted with two cutting blades apiece. These inserts are single-sided. Cast iron, alloy steel, and stainless steel are all suitable materials for use in the robust geometry’s design, which allows for their use. Fabricated using APMT 1135 insert material of the best quality, which has a high level of both longevity and durability. The cutting edge of the blade, which is made using imported tungsten APMT 1135 insert, is able to make clean cuts due to its extremely high level of hardness and endurance. This, in turn, reduces the amount of wear that is experienced by the cutter, which lengthens the amount of time that the tool can be used effectively. It will not be difficult for you to find the location on the cutting surface that matches to the Huana APMT insert that you are using when you do so since this will be done.
The AMPT1135, 1604, and RPMT1204 inserts all include a positive molded chip breaker that is precision-molded into the I.C. of the insert. They feature a relief angle of 11 degrees and a cutting edge that has been polished to a sharp point. They have screw holes that were manufactured in accordance with ISO standards. In most contexts, it is understood to have two slicing edges. On the other hand, each of them has four distinct cutting edges. When they are put on 90° indexable milling cutters, and both of the edges become dull, they may be mounted on 75° indexable milling cutters, and further milling operations can be carried out using the other two edges. Suitable for use in the processing of iron, steel, and stainless steel components.
Inserts with a cutting edge that is less than ninety degrees are able to sit flat in the insert holder thanks to the positive-rake function. This results in increased cutting clearance and a better finish than inserts with the negative-rake feature. Only one side of the inserts has cutting edges. They have a TiN coating, which makes them more durable than inserts that do not have this coating and allows them to operate at higher rates than uncoated inserts.
- Turning inserts
Turning inserts are available in a wide range of forms, sizes, and thicknesses. It is possible for the form to be round in order to optimize the edge’s strength, diamond-shaped in order to permit a sharp point to cut delicate features, square, or even octagonal in order to enhance the number of distinct edges that may be applied as one edge after another wears out.
- WNMG turning insert

Aluminum is only one of the many various kinds of materials that may be used to construct them. The wear resistance and corrosion resistance of MGMN aluminum inserts such as VCGT, CCGT are among the best in the industry.
- U Drill Inserts: SPMG, WCMX
The WCMX insert is not only affordable but also has a good drilling efficiency. Peach-colored and versatile, this insert may be utilized on all three sides. The drilling efficiency is comparable to that of an SPMG type, although it is somewhat superior. Although the bottom hole of the U drill SPMG insert is flat in relation to the WCMX, it is not quite flat. SPMG inserts have a square shape and four cutting surfaces; the finish on these inserts is superior to that of WCMX.
- Rapid feed Inserts: WNMU, SNMU, LNMU
In order to produce a straight surface free of cusps, rapid feed inserts such as WNMU, SNMU, and LNMU are used; however, the width of cut must not be more than DC. Cutting diameter maximum. Maximum ramping angle.
Conclusion
It is vital to use the suitable form of an insert with its uses, and this shape is decided by the optimum point angle for maximum strength and economic efficiency. The requirements of the application as well as the amount of room available in the application for the cutting tool will determine the appropriate size of the insert. Large insert sizes call for more stability while working with large machines; the usual insert size may generally grow up to 25 millimeters. After the project is finished, the height of rotation may often cause a reduction in the size of the insert.
