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.
Oxide, also known as black oxide or steam oxide, is a surface treatment that prevents chip building, galling and welding on the workpiece. It is commonly used on low carbons, stainless steel and ferrous metals.
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.
