Descripción del producto

DIN**8 Twist Drill Bits HSS-R HSS-G HSS Cobalt

Short twist drills have a rank angle (sometimes referred to as angle of twist) of *7°, a point angle between **8° and **5° as well as a cylindrical shank. Type N is suitable for standard chipping materials. A distinction is made between roll forged and fully ground twist drills, depending on the production process.

When producing roll forged drills, the slugs are heated and formed into spiral coils. Fully ground drills get their spiral coil cut while being fully hardened. For a better distinction between the diff erent types of twist drills, the following finishes are assigned to the different drills:
