Features and Benefits
Bottoming chamfers are used for threading blind holes. They have 1 to 2 threads.
Nitride/oxide is harder than oxide and is used to prevent galling, welding and loading. It is commonly used on low carbon steels, stainless steels and nonferrous metals.
High Speed Steel (HSS) provides good wear resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
