Features and Benefits
Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.
Titanium carbonitride (TiCN) is harder and more wear resistant than TiN. It is used on stainless steels, cast iron and aluminum alloys.
High Speed Steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
