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.

Key Features

  • Size Range: Available in 3/8", 1/2", 9/16", 5/8", 3/4", 7/8", and 1" diameters, each 17" in overall length, for deep-hole boring through dimensional lumber and framing members on job sites of every scale.
  • Durable Construction: High Speed Steel body with a WeldTec hard cutting edge welded to the base material, giving the bit greater strength and a longer cutting life than standard ship augers.
  • Patent Pending Welded Cutting Edge: Delivers 2X the nail cutting life of standard Irwin ship augers, holding an edge through tougher job-site conditions and embedded fasteners.
  • 7/16" Quick-Change Impact Shank: Standard across the size range, allowing fast bit swaps and full compatibility with impact-ready drills and drivers for job-site efficiency.
  • Wide Flutes: Improve chip and debris removal along the full length of the bit for faster, cleaner, more efficient boring in dimensional lumber.

Irwin 3043004 – Frequently Asked Questions

1) What sizes does the Irwin 30430 WeldTec wood auger come in?
Seven diameters: 3/8, 1/2, 9/16, 5/8, 3/4, 7/8 and 1 inch, and all of them are 17 inches overall. That length is what lets you bore through stacked framing members, double top plates and built-up headers from one side. If you need something shorter for tight bays, this family does not offer it; 17 inches is the only length.
2) What is the difference between a WeldTec auger and a standard Irwin ship auger?
Both are long wood-boring augers, but the WeldTec version adds a hard cutting edge welded onto the High Speed Steel body instead of relying on the base steel alone, and Irwin puts the nail cutting life at double that of their standard ship auger. Sizes 3/4 inch and up are also fully forged. If you are boring clean new lumber only, a standard ship auger does the job; the welded edge earns its keep in demo and remodel work.
3) Is the Irwin WeldTec auger self-feeding?
No. The WeldTec auger is not a self-feed bit, so you supply the feed pressure rather than letting a lead screw pull the bit in. That matters on a cordless impact driver, where a self-feeding bit can stall or torque the tool out of your hands. Wide flutes clear the chips as you push.
4) Which WeldTec auger size should an electrician use for running cable through studs?
For standard NM cable runs through studs and joists, electricians typically pull the 3/4 or 1 inch from this range, with 9/16 and 5/8 covering lighter single-cable runs. The 3/4 inch and larger sizes have a fully forged body for extra rigidity under heavy boring loads, which is the half of the range that holds up best to repeated deep holes.
5) Is the Irwin 30430 auger sold as a single bit or a set?
Each size is sold individually, not as a kit, and it ships without a case. You order the diameter you need by part number, for example 3043005 for the 1/2 x 17 inch and 3043009 for the 3/4 x 17 inch.
6) Where are Irwin WeldTec auger bits made?
Brazil. That is the stated country of origin across the WeldTec auger range, which is the detail procurement teams need for sourcing documentation.
