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 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.
Uncoated tools do not feature supportive treatments on the cutting edge. They are are used at reduced speeds for general applications on nonferrous metals.
Spiral flutes are constructed of a high flute angle to remove chips more easily.
