Features and Benefits
Semi-bottoming chamfers are used for blind holes. They have 3 to 3-1/2 threads.
Titanium carbonitride (TiCN) is harder and more wear-resistant than TiN. It is commonly 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 non-ferrous materials.
