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.
High Speed Steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
Titanium carbonitride (TiCN) is harder and more wear resistant than TiN. It is commonly used on stainless steels, cast iron and aluminum alloys.
Spiral flutes are constructed of a high flute angle to remove chips more easily.
