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.
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.
