TPMT 2(1.5)0.5-MM GS3115 Turning Insert - milling insert tpmt

The polycrystalline cubic boron nitride (CBN) inserts offer a high level of hardness, as well as thermal shock resistance. Although CBN’s exceptional toughness/hardness is still less than the diamond-based materials, it provides superior resistance to high temperatures. They can be used at very high cutting speeds.

This makes CBN inserts the ideal cutting material for machining of hardened steels (45-72 HRC) of any kind: Case hardened steel, tool steel, heat treated steel, etc. Additionally, it is also well suited to the machining of applications in which carbide and ceramic cutting tools often reach their limits, such as cast materials, and special alloys. They are compatible with standard tool holders by other, leading manufacturers.
