Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
Vanadium High Speed Steel (HSSE) is made of high speed steel, carbon, vanadium carbide and other alloys to increase abrasive wear resistance and toughness. It is commonly used on stainless steels and high silicon aluminums.
Nitride is a thin, hard-shell coating that supports the surface hardness of the tool. It is used where abrasive or wearing conditions exist.
