Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 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.
Fast Spiral Flutes with 40-53 degree angles are suitable for ductile materials like aluminum and copper; medium to high carbon steels and free machining stainless steels.
