Diablo Auger Bit for Wood & Nail-Embedded Wood – 1-1-2 Inch Diameter, 7-1-2 Inch Length, 7/16 Inch Hex Shank

Meet the Diablo Auger Bit for Wood & Nail-Embedded Wood. With a 1-1-2 inch diameter and a total length of 7-1/2 inches, this bit is designed to reach deeper into dense boards while preserving control and accuracy. The 5-1/2-inch working length lets you drill clean holes in thick pieces without repositioning as often, making it a practical choice for framing, remodeling, and carpentry tasks.

Built for challenging work, this auger leverages a thoughtful combination of cutting geometry and robust materials to support reliable performance. The two-step cutting action helps deliver precise holes in both clean wood and nail-embedded wood, reducing tear-out and the need for touch-up work. The Dura-Tip technology adds rugged durability, helping the tip resist wear when nails are present and minimizing premature dulling. A dual cutting edge supports smooth drilling, even when nails are encountered, so you can maintain a steady pace through tough sections. Deep flutes assist with chip evacuation, which can translate to more holes per charge and cooler operation during longer sessions. The quick-change 7/16-inch hex shank enhances stability and durability in both cordless and corded tools, keeping your setup tight and confident as you work.

In everyday use, this Diablo auger bit shines on projects that mix wood with nails, such as cabinetry repair, deck work, or structural framing where older boards may show nail lines. The design encourages clean starts and predictable hole diameters, helping you prepare for fasteners or fittings without compromising the surrounding surface. You may notice smoother starts, reduced resistance, and a more controlled feed as you drill deeper into thicker boards.
