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.
Oxide, also known as black oxide or steam oxide, is a surface treatment that prevents chip building, galling and welding on the workpiece. It is commonly used on low carbons, stainless steel and ferrous metals.
