The Diablo 3/4 in. x 17-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is a professional-grade boring bit engineered by Diablo for demanding wood drilling tasks including wood framing, stacked furniture assembly, gardening, and plumbing applications. Designed with a two-step cutting action and a self-feeding Dura-Tip, this auger bit drives itself through clean lumber, hardwoods, softwoods, plywood, and even nail-embedded wood with effortless control and consistent hole quality. The 7/16 in. hex quick-change shank makes it fully compatible with cordless and corded drill drivers, giving tradespeople and contractors a fast, reliable solution for high-volume boring tasks where bit life and chip clearance matter most.

Key Features

• Two-step cutting action - creates precise, clean holes in wood drilling applications, reducing tear-out and rework on both clean lumber and nail-embedded wood
• Self-feeding Dura-Tip - pulls the bit forward automatically for extreme durability in nail-embedded wood, reducing operator push force and extending bit service life
• Dual cutting edge design - delivers effortless, smooth hole drilling even through nails embedded in framing lumber, minimizing binding and bit deflection
• Deep flutes - accelerate chip removal from the bore hole, keeping the cutting zone clear for more holes per battery charge on cordless tools
• 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 additional tools
• 17-1/2 in. overall length with 13-1/2 in. working length - reaches deep into framing cavities and stacked materials for plumbing, electrical, and structural boring without awkward extensions

Why This Product

• Contractors and framers working through nail-embedded lumber can rely on the Dura-Tip and dual cutting edge to keep drilling without stopping to extract or reposition - a direct productivity advantage on busy job sites
• The deep flute design clears chips aggressively, which means fewer interruptions per battery charge - a practical benefit when drilling multiple holes through stacked framing or plywood
• With a 3/4 in. diameter and a 13-1/2 in. working length, this auger bit covers common rough-in bore sizes for plumbing and electrical trade work through deep framing members
• The 7/16 in. hex quick-change shank fits standard drill drivers and impact wrenches without adapters, making this bit a versatile addition to any wood framing, gardening, or general construction toolkit

Frequently Asked Questions

Can this auger bit drill through wood that contains nails?

Yes. The Diablo DAG3070 is specifically engineered for nail-embedded wood applications. The Dura-Tip and dual cutting edge work together to drive through nails encountered in reclaimed lumber, framing, and stacked materials without stalling or excessive bit wear.

What shank type does the DAG3070 use, and which tools accept it?

The DAG3070 features a 7/16 in. hex quick-change shank. This shank design is compatible with standard cordless and corded drill drivers and impact wrenches, and allows for fast bit changes without extra tools or adapters.

What is the usable working length of this auger bit?

The working length - the portion of the bit that actively bores into the material - is 13-1/2 in. The overall bit length is 17-1/2 in. This reach is well-suited for boring through deep framing members, stacked materials, and rough-in plumbing or structural applications.

What wood materials can this auger bit be used on?

The Diablo DAG3070 is rated for use in hardwoods, softwoods, plywood, and nail-embedded wood. It is designed for wood framing, stacked furniture, gardening, and plumbing applications where clean, accurate holes are required in a variety of lumber types.
