Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
High Speed Steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
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.
