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.
WD1 is a multi-layer coating that is harder and more resistant to heat than TiAIN. It is commonly used on medium-to high-carbon steel and other difficult-to-machine materials. WD1 is a proprietary coating exclusive to OSG Tap and Die, Inc.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
