CBN tools


Highly-reliable tools optimized for machining ferrous materials


PCBN (polycrystalline cubic boron nitride) cutting tools enable the machining of ferrous materials, which are difficult to work with diamond tools. CBN is second only to diamond in terms of hardness and thermal conductivity, making CBN tools suitable for machining alloy steel and cast iron of 45 HRc and above.

Most CBN cutting tools use inserts and bites. They are used for machining ferrous metals such as hardened steel, cast iron and sintered metal, and enable machining with greater speed and precision than carbide tools while providing excellent durability. 

CBN end mills

CBN end mills

Increases in the spindle speed of machine tools have led to demand for faster machining. High-precision machining at high rotation speeds has also increased demand for CBN end mills.
CBN end mills are more wear-resistant than carbide end mills and do not exhibit increased wear even at machining high speeds.

CBN ball end mills

CBN ball end mills

While conventional metal machining requires several carbide end mills, CBN ball end mills can be used for free-form surface machining of small precision metal dies and enable machining with a single tool. They also increase tool durability and reduce the required working time.
