ARTU Multi-Purpose Drill Bit Demo
The original multi-purpose drill bit. Special negative back grinding enables the tip to bore through materials with a filing action rather than a cutting action. The tip is a blend of Cobalt and Tungsten Carbide designed for maximum hardness and resistance to heat and wear. The shank is made of Chrome Vanadium Steel for enormous strength and flexibility. Can be used in corded or cordless drill motors with rotary or percussion drilling. Can also be used in a drill press.
