Features and Benefits
Modified bottoming chamfers similar to bottoming chamfers, but longer and have more teeth. They are used for threading to the bottom of blind holes and constructed of 2 to 2-1/2 threads.
Spiral flute taps are used for threading blind holes in aluminum, brass and softer steels. The flute geometry draws the chips away from the hole where chip disposal may be an issue.
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.
High Speed Steel (HSS) provides good wear-resistance and can be used in general purpose applications for both ferrous and nonferrous materials.
