cbn_leftoftextFor over 50 years, Kyowa has strived to continually develop high quality, high precision products for their customers.

Their ATTACKSMITH brand of cBN end mills reflects this forward thinking approach by providing enhanced performance and faster cutting speeds when compared to ordinary carbide end mills.



Developed to machine hardened steels between 40 and 70 HRC, Kyowa’s cBN end mills are spiral fluted for longer tool life and are second only to diamond on the hardness scale, providing increased stability at higher temperatures.
