Features and Benefits
High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and nonferrous materials.
Oxide prevents chip building, galling and welding on the workpiece. It is commonly used on low carbons, stainless steel and iron based ferrous metals.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
