Item #: 57600686Brand: Cle-ForceModel #: C69077 Features and Benefits High speed steel (HSS) provides good wear resistance and can be used in general purpose applications on both ferrous and nonferrous materials. Oxide/Gold provides a polished finish and prevents chip building, galling and welding on a workpiece. It is commonly used in several applications on low carbons, stainless steel and iron based ferrous metals. Straight shanks are used for general purpose applications. The shank is smaller than the drill bit diameter. They are used with portable drills and drill presses on ferrous and non-ferrous materials. Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts. Regular, also known as medium spiral bits, are used in general purpose applications. They are used on soft, nonferrous materials.
