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.
