Features and Benefits
High speed steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
Nitrided land increases durability on the raised spiral areas at the end of the drill bit. It is commonly used on aluminum with a high silicon content, brass, cast iron, plastics and mild steels
Parabolic flutes are constructed with a wider flute shape for increased chip flow.
