Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
Nitride is a thin, hard-shell coating that supports surface hardness of the tool. It is commonly used where abrasive or wearing conditions exist.
Slow Spiral Flutes with 8-20 degree angles are used for tough materials like high nickel alloys, titanium and some series of stainless steels.
