One-piece hex-shank impact drills from 3 mm to 13 mm — lock straight into impact drivers. The solid 1Pc shank transfers full impact torque without the wobble or joint failure of two-piece designs, drilling metal and wood fast with quick-change convenience. Factory-direct from a 20-year precision-tools manufacturer with ISO 9001 / 14001 / 45001 triple-system certification.
