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 is a multi-layer coating that 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 with a higher flute angle to remove chips more easily.
