Meet the Diablo DAG2120 1-1/8\" x 13\" Auger Bit for Wood & Nail-Embedded Wood — a purpose-built solution for clean, precise holes when nails and dense lumber stand in the way. This long, robust auger is ready for serious woodwork where standard bits struggle with embedded metal and reclaimed boards.

Key advantages you’ll notice on the job

• 1-1/8" diameter, 13" length designed for large bore holes in deep workpieces, reducing the need for multiple passes.
• Two-step cutting action delivers precise, clean holes, even in variable wood grain, minimizing splintering and tear-out.
• Self-feeding Dura-Tip pulls the bit into the wood, maintaining a controlled start and helping you progress smoothly when nails are encountered.
• Dual cutting edge provides an effortless, smooth drilling experience in nail-containing wood, reducing stalling and binding.
• Deep flutes optimize chip evacuation for faster drilling and more holes per charge, so you spend less time clearing scraps.
• Quick change shank enhances stability and durability with both cordless and corded impact wrenches and drill drivers, making swaps quick and secure.

Ideal use cases and who benefits most

• Professionals working with reclaimed or nail-prone lumber who need reliable hole quality for fasteners, wiring passes, or dowel joints.
• Electricians and builders drilling through wooden studs or structural members that may harbor nails, screws, or other fasteners.
• Woodworkers and DIY enthusiasts tackling furniture projects, decks, or cabinetry where clean, accurate holes are essential for fit and finish.

Practical guidance to get the most from your auger bit

• Let the chip flow do the work—withdraw periodically to clear debris and keep cutting efficiency high.
• Use a steady, moderate speed and light to medium pressure to maintain control, especially when nails are present.
• Pair with a compatible drill or impact driver equipped with a quick-change shank for seamless operation and reduced bit wobble.

If your projects routinely involve reclaimed lumber, nails, or mixed-grain wood, this 1-1/8\" x 13\" bit is the dependable choice that helps you finish faster with professional-grade holes.
