The HSS Impact Control twist drill provides exceptionally robust drilling in metal, especially in combination with impact drills. The powerful body is extremely sturdy. It is made from solid metal and features an oxide-coated flute that gives it excellent surface quality for material cutting with reduced wear. Suitable for use in alloyed and non-alloyed steel, cast iron, sintered iron, non-ferrous metals, thin sheets, and plastics. The drill is compatible with a 1/4-inch hex shank system for general use with drill drivers, impact drills, and drill stands.
