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 steels and difficult-to-machine materials. WD1 is a proprietary coating exclusive to OSG Tap and Die, Inc.
Spiral flutes are constructed with a higher flute angle to remove chips more easily.
