Product Description
The Diablo 1-1/4 in. x 17-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is a professional-grade boring tool engineered by Diablo to deliver maximum performance and extreme durability when drilling through clean wood, nail-embedded lumber, hardwoods, softwoods, and plywood. Designed for wood framing, plumbing rough-ins, stacked furniture assembly, and gardening applications, this long-reach auger bit combines a self-feeding tip with a dual cutting edge to make deep, clean holes fast - even when nails are in the way.
Key Features
- Two-step cutting action for precise, clean holes in wood drilling applications - produces accurate, splinter-minimized bores through a wide range of wood materials so you spend less time cleaning up edges
- Dura-Tip self-feeding point for extreme durability in nail-embedded wood - pulls the bit forward automatically and resists damage from hidden fasteners, reducing downtime and bit replacement costs
- Dual cutting edge design for effortless, smooth hole drilling in nail-embedded wood - reduces the force required on the tool so operators experience less fatigue during extended framing or plumbing work
- Deep flutes for fast chip removal - evacuates wood chips quickly out of the bore, keeping the hole clear and allowing more holes per battery charge when using a cordless drill driver
- 7/16 in. hex quick change shank increases stability and durability in cordless and corded impact wrenches and drill drivers - locks securely into compatible chucks for a wobble-free drilling experience and long-term shank integrity
Why This Product
- Built specifically for nail-embedded wood - the Dura-Tip and dual cutting edge work together to push through lumber with hidden nails, making this bit a practical choice for demolition, remodeling, and retrofit framing where pulling every nail first is not realistic
- Long 17-1/2 in. overall length with a 13-1/2 in. working length allows the bit to reach deep into wall cavities and floor assemblies for plumbing, electrical, and framing rough-in tasks without repositioning
- The 7/16 in. hex quick change shank is compatible with both cordless and corded drill drivers and impact wrenches, giving tradespeople the flexibility to use the tools already on their belt without adapters
- Deep flute geometry extends productivity per battery charge by clearing chips efficiently - a real advantage on large framing or plumbing jobs where dozens of holes must be drilled in a single session

Frequently Asked Questions
Can this auger bit be used with an impact driver or wrench?
Yes. The 7/16 in. hex quick change shank is designed to increase stability and durability in both cordless and corded impact wrenches and drill drivers, making it compatible with a wide range of common jobsite tools.
What types of wood materials can this bit drill through?
This Diablo auger bit is designed to drill through hardwoods, softwoods, nail-embedded wood, and plywood. The Dura-Tip and dual cutting edge are specifically engineered to handle lumber that contains embedded nails without requiring pre-removal of fasteners.
How long is the working length of this auger bit?
The working length - the portion of the bit that actively bores material - is 13-1/2 in. The overall bit length is 17-1/2 in., providing the reach needed for deep wall, floor, and structural drilling tasks common in framing and plumbing work.
How do the deep flutes on this bit benefit cordless tool users?
The deep flutes are designed to enhance chip evacuation, clearing wood debris out of the bore quickly and efficiently. Faster chip removal means the bit cuts with less resistance, which helps extend the number of holes you can drill per battery charge - an important advantage during high-volume framing, plumbing, or gardening projects.
