Polycrystalline Diamond (PCD)

Our tools with cutting edges made of polycristalline diamond (PCD) are suitable for the machining of non-ferrous metals such as aluminum alloys, magnesium, copper, of reinforced plastics (GFK/CFK etc.), graphite and ceramics as well as hard metals (green machining).

Cubic Boron Nitride (CBN)

For the machining of hardened steel, sintered metals and cast iron we offer tools with cutting edges made of cubic boron nitride.

Natural Diamond (ND)

Our tools with cutting edges made of natural diamond are suitable for the machining of high-quality technical surfaces as well as for the polish turning in the jewelery and watch industry.

Our indexable inserts are available according to the ISO standard
