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 can be found with ranges between 2 to 2-1/2 threads. Some modified bottoming chamfers are 2-1/2 to 3 threads.
Nitride is a thin, hard-shell coating that supports surface hardness of the tool. It is commonly used where abrasive or wearing conditions exist.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
