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.
Bottoming chamfers are used for threading blind holes to the bottom. They have 1 to 2 threads.
