Carbide Insert

Carbide insert is the indexable insert widely used in CNC lathes, mainly applications including metal turning, milling, threading and drilling. Cemented carbide inserts have much advantage in high efficiency which can be four times more than traditional welding blade or alloy blade in real production.

Betalent carbide make carbide make standard carbide turning inserts, for example classical turning inserts DCMT11T304, DCMT11T308, WNMG080404, WNMG080408, WNMG080404R, WNMG080408R, TNMG160404R, TNMG160404R, TNMG160404R/L-VF, TNMG160408R/L-VF, DCMT11T304-MT, DCMT11T308-MT, TCMT090202MT, TCMT090204MT,CCMT09T304-MT, CCMT09T308-MT, WNMG080404-43, WNMG080408-43, WNMG080404, WNMG080408, and classical milling insrts RPMW1003, APMT1135PDER-M2, APMT1135PDER-H2, RPMT1204-JS, APMT1604PDER-M2, APMT1604PDER-H2, APMT1135, RPMT1204, APMT1604. We also developed series of carbide inserts for steel, cast iron, aluminum and high hardness steel.

Carbide Inserts Related FAQs

Q What are carbide inserts made of?

Carbide inserts are maily made of sintered untra fine grain tungsten carbide and colbalt.
Q Is carbide stronger than steel?

Yes, the hardness of common tool steel is around 55HRC to 66HRC, general sintered untra fine grain size carbide is above 91HRA, close to 77HRC, much higher than steel, which performs much better in making inserts.
Q How do I choose a carbide insert?

Choose the proper geometry insert for your detailed application. Choose the proper grade of the insert. To choose a proper carbide grade, the precondition is that the insert can be applied to the cutting without chip broken very soon, you can choose the harder carbide insert to get a longer tool life, the harder, the higher wear resistance, but keep the precondition in mind because too hard carbide grade can cause this problem.
Q How long should a carbide insert last?
There are some factors relative to the tool life of a carbide insert:
1. The concentricity of the cutter head, carbide inserts correctly fixed in the very precise cutter head which without abnormal vibration can last longer.
2. Carbide applied to make carbide insert, choose the proper hard origin carbide as the raw material to manufacture insert can make the carbide insert lasts longer.
3. Geometry, choose the proper insert geometry to the application.
4. Carbide insert manufacture technology is continually improved, you can get a satisfying tool life of carbide insert for one concerned application, and along with the improvement of carbide insert manufacture technology, the carbide insert can last longer and longer for one concerned application.
Q What are carbide inserts used for?

Carbide inserts are used for cutting various metals, such as steel, cast iron, aluminum, copper, and other metals of which hardness is between 30HRC to 65HRC.
