Irwin 49915 15/16 In. Solid Center Auger with Cutting Spur, I-100 Series

The Irwin 15/16 In. Solid Center Auger with Cutting Spur, part of the I-100 Series, is a full-length, heat-treated wood boring bit engineered for heavy-duty jobs without bending. Measuring 15/16 in. in diameter with a 7.5 in. overall length (OAL), this auger is built for both soft and hard wood applications on demanding jobsites. This 15/16 In. auger bit is well suited for framing, decking, and general construction boring tasks where dependable, splinter-free holes are required. The coarse screw point allows for fast boring, while the single cutting spur scribes the outside of the hole for a smooth finish, and the solid-center design adds extra rigidity for straight, dependable drilling from start to finish. As a non-energy using accessory bit, it is designed to be chucked into a standard corded or cordless drill for hand-operated boring work.

Irwin 49914 – Frequently Asked Questions

1) What sizes does the Irwin I-100 solid-center auger bit come in?
Two diameters in the I-100 solid-center auger line: 7/8 inch (part 49914) and 15/16 inch (part 49915). Order by the part number to be sure you get the diameter you want, since the two are only a sixteenth apart and easy to mix up in a bit roll.
2) Can I run this Irwin auger bit in a cordless drill, or does it need a brace?
It is made to be chucked into a standard corded or cordless drill for hand-operated boring. No power source of its own, no battery. The coarse screw point pulls the bit into the wood, so a drill with decent low-speed torque and a side handle is the right tool, not a high-speed trim driver.
3) Will an Irwin I-100 auger bit drill clean holes in hardwood, or is it only for framing lumber?
Both. The coarse screw point drives fast through soft and hard wood, and the single cutting spur scribes the perimeter of the hole ahead of the cutting lip so the rim comes out clean instead of splintered. Typical use is framing, decking, fence and post work, timber boring and general woodworking.
4) What does solid-center mean on an auger bit and when should I choose one over a hollow-center auger?
Solid center means the core of the bit is a continuous shaft with the flute wrapped around it rather than an open spiral. That stiffness is what keeps the hole straight and stops the bit wandering or flexing in heavy boring. Pick solid center for framing, posts and running wire through structural lumber. An open-throat or hollow-center auger clears long stringy chips better in deep green timber, but it gives up rigidity.
5) Are Irwin 49914 and 49915 auger bits sold individually or by the case?
Each bit is packaged individually, and the case pack is 24 each. An electrician or framer buying one or two gets a single bit; a distributor or MRO stockroom standardizing on one diameter can take the full 24-piece case.
6) Where is the Irwin I-100 auger bit made?
Brazil. That matters on public and institutional jobs where country of origin has to be recorded on the submittal or the purchase order.
