Features and Benefits
Plug chamfers are the most commonly used chamfer and are designed for efficiently threading through and blind holes. They have 3 to 5 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.
