The Impact Wood Auger Bits – Long Series from Milwaukee Tool are engineered for deep drilling in wood using corded or cordless drills, including impact wrenches, allowing easier one-handed and overhead operation with reduced kickback risk. Featuring a special zone-hardened shank for durability, a Through-Center head for continuous, efficient chip removal, and a polished 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 ideal for hard and soft wood, treated timber, plywood, chipboard, WPC, laminated beams, and exotic hardwoods such as oak, teak, iroko, and bongossi.
