Irwin WeldTec Auger Wood Drill Bit, High Speed Steel
The Irwin WeldTec Auger Wood Drill Bit is a High Speed Steel auger engineered for professional wood boring applications, available in trade sizes from 3/8" up to 1" in diameter, with every size finished at a 17" overall length for reaching deep into dimensional lumber and framing members. Each bit in this lineup features a WeldTec hard cutting edge welded to the base material, giving the auger improved strength and an extended cutting life compared to standard ship augers. A 7/16" quick-change impact shank is standard across the range, letting crews switch bits quickly on impact-ready drills and drivers. Wide flutes speed chip clearance for smoother boring, making this auger family a dependable choice for framing crews, remodelers, and general construction drilling.
