Product Description
The Diablo 9/16 in. x 17-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is a professional-grade boring bit engineered by Diablo for demanding wood drilling tasks including framing, plumbing rough-in, and stacked furniture work. Designed to handle both clean lumber and nail-embedded wood with equal confidence, this auger bit combines a self-feeding tip, dual cutting edges, and deep chip-clearing flutes to deliver fast, accurate holes with less effort. Whether you are drilling through softwoods, hardwoods, plywood, or wood hiding embedded nails, this bit is built to keep working where lesser bits fail.
Key Features
- Two-step cutting action - scores and clears material in a coordinated sequence, producing precise and clean holes in wood drilling applications without tear-out or wandering
- Dura-Tip self-feeding point - pulls the bit forward automatically and is built for extreme durability in nail-embedded wood, reducing push force required by the operator
- Dual cutting edge design - removes material on both sides of the bore simultaneously for effortless, smooth drilling through wood with nails
- Deep flutes - evacuate chips quickly and efficiently, keeping the hole clear for faster drilling and more holes per battery charge
- 7/16 in. hex quick-change shank - locks securely into cordless and corded drill drivers and impact wrenches, increasing stability and durability compared to round-shank alternatives
- 17-1/2 in. overall length with 13-1/2 in. working length - provides reach for deep framing, plumbing, and through-the-stud applications where a shorter bit cannot reach
Why This Product
- Purpose-built for nail-embedded wood - the Dura-Tip and dual cutting edges work together to bore through wood that contains nails without stopping to remove fasteners first, saving significant time on remodel and retrofit projects
- Compatible with the tools already on the jobsite - the 7/16 in. hex quick-change shank fits standard cordless drill drivers and impact wrenches, so there is no need for adapters or specialty chucks
- Deep flute design extends runtime between battery swaps - faster chip evacuation means less heat buildup and more holes per charge, which matters during high-volume framing, gardening, or plumbing rough-in work
- Versatile across common wood materials - rated for hardwoods, softwoods, plywood, and nail-embedded wood, making it a single solution for multiple material types encountered in wood framing and stacked furniture applications

Frequently Asked Questions
Can this auger bit drill through wood that has embedded nails?
Yes. The Diablo DAG3040 is specifically designed for nail-embedded wood. The Dura-Tip and dual cutting edge design work together to bore through wood containing nails, delivering effortless and smooth drilling performance even in these challenging conditions.
What type of shank does this bit use, and will it fit my drill?
This bit uses a 7/16 in. hex quick-change shank. It is compatible with cordless and corded drill drivers and impact wrenches that accept a 7/16 in. hex shank, which is a standard size on most professional and homeowner-grade tools.
What is the difference between the overall length and the working length?
The overall length of this bit is 17-1/2 in., which includes the full bit from tip to the end of the shank. The working length - the portion of the bit that actively cuts and removes material - is 13-1/2 in. This extended reach is useful for deep framing bores, through-wall plumbing runs, and other applications where a standard-length bit cannot reach the target depth.
What wood materials is this auger bit rated to drill?
The Diablo DAG3040 is rated for use in hardwoods, softwoods, plywood, and nail-embedded wood. It is suited for wood framing, stacked furniture, gardening, and plumbing applications where a variety of wood types and conditions may be encountered.
