Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 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.
V is a multi-layered TiCN coating that is harder and has greater wear resistance than TiN. It is used for applications in cast iron, steel, stainless steel, nickel alloys and aluminum. V is a proprietary coating exclusive to OSG Tap and Die, Inc.
