The Diablo 1/2 in. x 17-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is a professional-grade drilling solution engineered by Diablo for demanding wood framing, plumbing rough-in, stacked furniture assembly, and gardening applications. Designed to handle everything from clean softwoods and hardwoods to plywood and nail-embedded wood, this auger bit combines a self-feeding tip, dual cutting edges, and deep chip-clearing flutes to deliver fast, accurate, and fatigue-reducing performance in both cordless and corded drill/driver setups.

Key Features

• Two-step cutting action for precise, clean holes in wood drilling applications - reduces tear-out and produces cleaner results in hardwoods, softwoods, and plywood without extra cleanup time
• Dura-Tip self-feeding point for extreme durability in nail-embedded wood - pulls the bit into the material automatically so the user applies less manual pressure, reducing fatigue during repetitive drilling tasks
• Dual cutting edge design for effortless, smooth hole drilling in nail-embedded wood - maintains cutting performance even when nails are encountered, keeping the job moving without stopping to swap bits
• Deep flutes for fast chip removal - evacuates waste material quickly to reduce heat buildup and allow more holes per battery charge on cordless tools
• 5/16 in. hex quick change shank increases stability and durability in cordless and corded impact wrenches and drill drivers - drops into standard quick-change chucks in seconds for faster bit swaps on the job site

Why This Product

• Built specifically for nail-embedded wood - the Dura-Tip and dual cutting edge work together to power through wood that contains embedded nails, making this bit a reliable choice for remodeling and demolition-adjacent framing work where pulling every nail first is not practical
• The 17-1/2 in. overall length with a 13-1/2 in. working length gives the reach needed for through-wall plumbing and wiring rough-in tasks without requiring extension attachments
• Deep flutes actively clear chips during drilling, helping cordless tool users get more holes from a single charge - a practical advantage during large wood framing or stacked furniture drilling projects
• The 5/16 in. hex quick-change shank is compatible with standard drill/driver chucks, delivering a secure, wobble-free fit that improves hole accuracy and extends the working life of both the bit and the tool

Frequently Asked Questions

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

Yes. This bit is specifically designed for nail-embedded wood applications. The Dura-Tip provides extreme durability when contact with nails occurs, and the dual cutting edge maintains smooth, effortless drilling even in wood containing embedded fasteners.

What type of shank does this bit use, and is it compatible with impact drivers?

This auger bit features a 5/16 in. hex quick-change shank, which is compatible with both cordless and corded impact wrenches and drill drivers. The hex shank design increases stability and durability and drops into quick-change chucks without 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 shank and cutting body. The working length - the portion that actively drills into the material - is 13-1/2 in. The extended reach makes this bit well suited for through-wall plumbing and framing applications where depth is a factor.

What wood materials is this auger bit rated for?

This bit is designed to drill hardwoods, softwoods, nail-embedded wood, and plywood. It is suited for wood framing, stacked furniture assembly, gardening, and plumbing applications where a consistent, clean hole is required across varying wood types.
