      • KC7030

        composition: A PVD TiN coated grade with a medium grain, 8.5% cobalt unalloyed substrate.
        application: The substrate of grade KC7030 has a large grain structure that improves toughness, while the
        reduced cobalt content increases wear resistance. The PVD TiN coating resists abrasive wear, reduces
        frictional heat, and preserves edge strength. These combinations make this grade ideal for machining
        long-chipping materials such as low-carbon steel, austenitic stainless steel and heat-resistant alloys.
        geometry: The cutting edge has a light hone and corner chamfer.

      • KC7135

        Composition: PVD TiCN/TiN coated medium-grain carbide with high toughness.
        Application: Used for KSEM™ PC pre-centering inserts in most materials. The highly wear-resistant TiCN coating combined with a tough carbide substrate are perfectly suited to help with pre-centering operations in metastable machining conditions.
