Features and Benefits
Modified bottoming is similar to bottoming, but the chamfer is longer and has 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.
Bright provides a smooth, polished finish on the tool. It increases chip flow in softer materials such as aluminum, wood and plastic.
