Features and Benefits
Taper chamfers also known as starter taps have a longer chamfer and require a less aggressive cutting action. They have 7 to 10 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.
