The Diablo 1/4 in. x 7-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is a precision-engineered boring tool built for demanding wood framing, plumbing rough-in, stacked furniture assembly, and gardening applications. Designed by Diablo for use in cordless and corded drill/drivers, this auger bit delivers clean, accurate holes through hardwoods, softwoods, plywood, and nail-embedded lumber - tasks that quickly wear out inferior bits. Whether you are boring through framing members that contain hidden fasteners or drilling clean passages in fresh dimensional lumber, this 1/4 in. auger bit is engineered to stay sharp and pull through material with minimal effort.

Key Features

• Two-step cutting action for precise, clean holes in wood drilling applications - reduces tear-out and produces professional-quality bores in both clean wood and nail-embedded stock
• Self-feeding Dura-Tip pulls the bit forward through material - eliminates the need for heavy downward pressure, reducing operator fatigue during repetitive drilling
• Dual cutting edge design for effortless, smooth hole drilling in nail-embedded wood - allows the bit to pass through embedded fasteners without stalling or damaging the workpiece
• Deep flutes for fast chip removal - accelerates debris evacuation to keep the bit cutting freely, delivering more holes per battery charge in cordless applications
• 3/16 in. hex quick change shank increases stability and durability in cordless and corded impact wrenches and drill drivers - snaps in and out of quick-change chucks without tools for faster bit swaps on the job

Why This Product

• Built specifically for nail-embedded wood - the Dura-Tip and dual cutting edge handle hidden nails and fasteners that would chip or bind a standard auger bit, making this the right choice for demolition framing and remodel drilling
• The 5-1/2 in. working length and 7-1/2 in. overall length give you the reach needed for framing, plumbing, and gardening tasks where standard short bits cannot access the drilling zone
• Deep flute geometry maximizes chip evacuation, which translates directly into longer run times per battery charge - a measurable advantage when drilling multiple holes in a single session
• The 3/16 in. hex quick-change shank is compatible with both cordless drill/drivers and corded tools, offering versatility across a wide range of job site equipment without additional adapters

Frequently Asked Questions

Can this auger bit drill through wood that has nails embedded in it?

Yes. The Diablo DAG1010 is specifically engineered for nail-embedded wood. The Dura-Tip and dual cutting edge design allow the bit to bore through lumber containing nails or fasteners, making it well suited for remodeling, demolition framing, and retrofit plumbing or electrical work where hidden fasteners are common.

What type of shank does this bit have and is it compatible with my drill?

This auger bit features a 3/16 in. hex quick-change shank. It is designed for use with cordless and corded drill/drivers and is compatible with standard quick-change chucks, allowing fast, tool-free bit swaps on the job site.

What is the usable working length of this bit?

The DAG1010 has a working length of 5-1/2 in. with an overall length of 7-1/2 in. This provides meaningful reach for framing, plumbing pass-throughs, and other applications where the drilling point needs to extend beyond the chuck into deep or obstructed spaces.

What materials can this auger bit drill through?

This Diablo auger bit is rated for use in hardwoods, softwoods, plywood, and nail-embedded wood. It is appropriate for wood framing, stacked furniture, gardening, and plumbing applications where clean, accurate holes are required across a variety of wood types.
