Item #: 60030921Brand: General ChipbreakerModel #: 2214314 Features and Benefits 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. Chipbreakers are designed with edges that break chip in to tiny pieces. The flutes are staggered to provide a smooth cut and are used where high speeds are required.
