As universal and proven as the material itself

The highest reliability

Our steel machining inserts distinguish themselves by their excellent cutting edge stability. This enables you to achieve great results every time.

Productive and economic

Thanks to the wear resistance of our carbides, the inserts achieve a long tool life; the insert geometry ensures high metal removal rates.

Versatile application

The inserts are suitable for a variety of different application fields – from low to high cutting speeds.
