Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
Cobalt is harder than high speed steel and provides better wear resistance. It is commonly used on high tensile alloys.
