The Diablo 7/16 in. x 17-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is engineered by Diablo to deliver maximum performance and extreme durability when boring through hardwoods, softwoods, plywood, and nail-embedded lumber. With a 17-1/2 in. overall length and a working length of 13-1/2 in., this auger bit reaches deep into framing, stacked furniture components, and plumbing or gardening installations where standard bits fall short. The self-feeding Dura-Tip and dual cutting edge work together to make clean, precise holes even in the toughest nail-embedded wood applications - giving contractors and DIYers alike a smooth, effortless drilling experience with a cordless or corded drill/driver.

Key Features

• Two-step cutting action for precise, clean holes in wood drilling applications - reduces tear-out and produces accurate bore diameters in hardwoods, softwoods, and plywood
• Dura-Tip self-feeding point for extreme durability in nail-embedded wood - pulls the bit forward automatically so less downward pressure is needed, reducing operator fatigue
• Dual cutting edge design for effortless, smooth hole drilling in nail-embedded wood - slices through hidden nails without stalling or damaging the bit prematurely
• Deep flutes for fast chip removal - efficiently clears debris from the bore hole so the bit runs cooler and delivers more holes per battery charge
• 1/4 in. hex quick change shank increases stability and durability in cordless and corded impact wrenches and drill drivers - snaps in and out without a chuck key, saving time on the job site

Why This Product

• Built specifically for nail-embedded wood - the Dura-Tip and dual cutting edge combination handles the nails that would stall or destroy a standard spade or twist bit, making it ideal for remodeling and wood framing work
• The 17-1/2 in. overall length and 13-1/2 in. working length let users reach through thick framing assemblies and stacked lumber without needing an extension, saving setup time in framing and plumbing rough-in applications
• Deep flutes actively evacuate chips during drilling, extending run time per battery charge - a direct advantage when using cordless drill/drivers for high-volume boring tasks in wood framing or gardening projects
• The 1/4 in. hex quick change shank is compatible with both cordless and corded impact wrenches and drill drivers, making this a versatile bit that fits the tools already on the job site

Frequently Asked Questions

Can this auger bit drill through wood that contains embedded nails?

Yes. The Diablo DAG3020 is specifically designed for nail-embedded wood applications. The Dura-Tip and dual cutting edge work together to bore through wood with nails efficiently, delivering an effortless and smooth drilling experience even in demanding remodeling and framing scenarios.

What shank size and type does the DAG3020 use, and is it compatible with impact drivers?

The DAG3020 uses a 1/4 in. hex quick change shank, which is compatible with both cordless and corded impact wrenches and drill drivers. The quick change design allows the bit to snap in and out without a chuck key and increases stability and durability during use.

What is the working length versus the overall length of this auger bit?

The overall length of this bit is 17-1/2 in., and the working length - the portion of the bit that actively bores through material - is 13-1/2 in. This extended reach makes it well suited for deep boring tasks in wood framing, plumbing rough-in, and stacked lumber applications.

What types of wood materials can this bit handle?

The Diablo DAG3020 is rated for use in hardwoods, softwoods, plywood, and nail-embedded wood. It is a practical choice for a wide range of tasks including wood framing, stacked furniture construction, gardening installations, and plumbing work.
