The Impact Wood Auger Bit Sets from Milwaukee Tool are designed for use with corded and cordless drills, including impact wrenches, enabling easier one-handed, overhead, and ladder drilling with reduced kickback risk. Featuring a special zone-hardening process for a durable tip and flexible body, a Through-Center head for efficient chip removal, and a Lewis flute design for fast waste ejection, these bits deliver smooth, clean, resharpenable cuts. With a 7/16″ shank (½″ square drive adaptor required), they are suitable for hard and soft woods, treated timber, plywood, chipboard, WPC, laminated beams, and exotic hardwoods such as oak, teak, iroko, and bongossi.
