Features and Benefits
Modified bottoming chamfers are similar to bottoming chamfers, but they are longer and have more teeth. They are used for threading blind holes and have 2 to 2-1/2 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.
Slow Spiral Flutes with 8-20 degree angles are used for tough materials like high nickel alloys, titanium and some series of stainless steels.
