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.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts.
