Features and Benefits
Solid carbide provides better rigidity than high speed steel. It is extremely heat-resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials.
ALTiN+ is a nano structured ALTiN coating with special additives. It has high hardness, protects against high temperatures and has exceptional oxidation stability. It is used on a broad range of materials including high temp alloys and stainless steels.
