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.
Powdered Metal (PM) is tougher and more cost effective than solid carbide. It is commonly used on highly abrasive materials including high silicon aluminums.
Hardlube is a multi-layered coating composed of titanium aluminum nitride and tungsten carbide/carbon (TiAIN/WC/C). It is stronger and more wear resistant than TIAlN. It is commonly used on steel, stainless steel, nickel and cobalt.
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.
