The Diablo DAG2110 1 in. x 13 in. Auger Bit for Wood & Nail-Embedded Wood is a heavy-duty auger bit built for boring large holes in clean wood and wood with embedded nails. This is a auger bit designed for wood boring in rough framing, remodel, and other drilling applications where hidden fasteners can show up. Model Number: DAG2110. If you need a 1-inch hole with the reach to get through thicker material, this bit is aimed at that job.

What makes this bit worth a look is how Diablo sets it up for real jobsite conditions instead of ideal lumber. The two-step cutting action is there to help create a more precise, cleaner hole, while the self-feeding Dura-Tip pulls the bit through the work so you are not forcing it every inch of the cut. Add in the dual cutting edge design, and the result is a smoother drilling feel in both standard wood and nail-embedded wood.

On deeper bores, chip control matters just as much as the cutting edge. The deep flute design is built to move chips out fast, which helps the bit stay cutting instead of packing up. That is especially useful when you are drilling repeated pass-through holes for rough work and do not want to waste time backing out constantly to clear the channel. Diablo also calls out more holes per battery charge, which makes sense when chip evacuation is doing its part instead of making the tool work harder than it has to.

The shank setup is another practical strength. This bit uses a 7/16 inch hex quick-change shank, which gives it a secure fit in corded and cordless impact wrenches and drill drivers that accept that interface. That extra stability matters on a 1-inch auger bit, because larger-diameter boring puts more load into the tool and bit than smaller general-purpose drill bits do. A solid shank connection helps reduce slip and keeps power transfer more consistent.

In terms of size, the 13-inch overall length and 9-inch working length give you useful reach for thicker assemblies and deeper pass-through drilling. That makes the Diablo DAG2110 a practical option when shorter auger bits come up short, but you do not need the extra length of the longest ship auger styles. For buyers comparing options, that working length is one of the more important specs on this bit because it tells you how much usable drilling depth you actually have.

This Diablo auger bit is best suited to users who regularly drill larger holes in wood framing members, nail-embedded material, or renovation stock where hidden metal is always a possibility. Contractors, remodelers, and serious DIY users who want a dedicated wood-boring bit with better durability in mixed material conditions will get the most out of it. If your work is mostly clean finish carpentry with shallow holes, this may be more bit than you need. If your work involves deeper boring and rough conditions, it is much more on target.

Diablo DAG2110 1 in. x 13 in. Auger Bit for Wood & Nail-Embedded Wood Gets the Basics Right

This is the kind of auger bit that makes sense when you are boring bigger holes in wood and do not want the job to stop the second the bit finds a hidden nail.

• Who it's for: Pros and serious DIY users drilling larger holes in wood framing, remodel material, or other stock where embedded nails are a real possibility.
• Why it stands out: The combination of a self-feeding Dura-Tip, dual cutting edge, deep flutes, and a 7/16 inch hex quick-change shank is built around smoother boring and better durability in rough work.
• Worth knowing: This is a single 1 inch auger bit, not a set, and the 13 inch length is useful when you need reach but may be longer than necessary for tight-space drilling.

• What material is this auger bit made to drill? It is designed for wood and nail-embedded wood applications.
• What is the usable drilling length? The listed working length is 9 inches.
• What shank does it use? It uses a 7/16 inch hex quick-change shank.
• Can it be used in cordless tools? Yes. Diablo lists it for use in corded and cordless impact wrenches and drill drivers that accept the shank size.
