Features and Benefits
Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 threads.
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.
Powdered Metal (PM) is tougher and more cost effective than solid carbide. It is commonly used on highly abrasive materials including high silicon aluminums.
