Features and Benefits
Semi-bottoming chamfers are used for blind holes. They have 3 to 3-1/2 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.
Titanium carbonitride (TiCN) is harder and more wear resistant than TiN. It is commonly used on stainless steels, cast iron and aluminum alloys.
