Features and Benefits
Modified bottoming is similar to bottoming, but the chamfer is longer and has 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.
