Features and Benefits
Plug chamfers are the most commonly used chamfer and designed for efficiently threading through and blind holes. They have 3 to 5 threads.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
Nitride/Oxide is used to prevent galling, welding and loading. It is commonly used on low carbon steels, stainless steels and nonferrous metals.
