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.
nano-A combines TiAlN and AlTiN coatings in a micro-layer structure that is harder and more wear resistant. It is used at high speeds on alloy steels, stainless steels and aerospace materials. nano-A is a proprietary coating exclusive to Guhring, Inc.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
