Features and Benefits
Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading blind holes and have 2 to 2-1/2 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.
