Product Description
The Diablo 3/4 in. x 7-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is a professional-grade boring tool engineered by Diablo for demanding wood framing, plumbing rough-in, stacked furniture assembly, and gardening applications. Designed to cut through hardwoods, softwoods, plywood, and nail-embedded lumber with equal confidence, this auger bit combines a self-feeding tip with a dual cutting edge geometry for fast, accurate hole drilling with minimal effort. Whether you are running conduit through framed walls or boring through stacked timbers, this 3/4 in. auger delivers clean, precise holes in even the most challenging material conditions.
Key Features
- Two-step cutting action - produces precise, clean holes in wood drilling applications, reducing tear-out and minimizing the cleanup needed after boring through hardwoods, softwoods, or plywood
- Self-feeding Dura-Tip - pulls the bit forward automatically for extreme durability and consistent penetration in nail-embedded wood, reducing the push force required from the operator
- Dual cutting edge design - delivers an effortless, smooth hole drilling experience in nail-embedded wood, maintaining cutting performance even when the bit contacts embedded fasteners
- Deep flutes - accelerate chip removal from the bore hole, reducing clogging and allowing more holes per battery charge when used with a cordless drill/driver
- 7/16 in. hex quick change shank - increases stability and durability in cordless and corded impact wrenches and drill drivers, enabling fast bit swaps without a chuck key
Why This Product
- Nail-embedded wood stops many standard auger bits cold - the Dura-Tip and dual cutting edge on this Diablo bit are specifically engineered to keep boring through lumber that contains nails, making it a reliable choice for demolition framing and reclaimed wood work
- The 7/16 in. hex quick change shank fits both cordless impact drivers and traditional corded drill/drivers, giving you flexibility across your existing tool inventory without adapters
- Deep chip-evacuation flutes mean fewer interruptions to clear the bore hole, which translates directly to faster completion times when drilling multiple holes through wood framing, plumbing rough-ins, or stacked timbers
- At 7-1/2 in. overall length with a 5-1/2 in. working length, this bit reaches deep enough for through-boring in typical framing lumber and dimensional stock without the need for a bit extension

Frequently Asked Questions
Can this auger bit be used with a cordless impact driver?
Yes. The 7/16 in. hex quick change shank is compatible with both cordless and corded impact wrenches and drill drivers, providing increased stability and durability across either tool type.
What materials can the Diablo DAG1090 auger bit drill through?
This bit is rated for use in hardwoods, softwoods, plywood, and nail-embedded wood. Its Dura-Tip and dual cutting edge design are specifically built to maintain performance when the bit contacts nails embedded in framing lumber or reclaimed wood.
How does the two-step cutting action improve hole quality?
The two-step cutting action works in sequence - the self-feeding Dura-Tip scores and pulls the bit into the material while the dual cutting edge follows to clear the full diameter of the hole. This combination produces holes that are precise and clean, reducing splintering and tear-out compared to single-step designs.
What is the usable working length of this auger bit?
The DAG1090 has a working length of 5-1/2 in. within its overall 7-1/2 in. body length, making it well suited for through-boring standard dimensional lumber used in wood framing and plumbing rough-in applications.
