Product Description
The Diablo 1-1/2 in. x 7-1/2 in. Auger Bit for Wood and Nail-Embedded Wood is engineered for demanding wood drilling tasks where precision and durability are non-negotiable. Designed by Diablo, this auger bit delivers maximum performance in both clean lumber and nail-embedded wood, making it a dependable choice for wood framing, plumbing rough-ins, stacked furniture assembly, and gardening applications. Whether you are boring through hardwoods, softwoods, plywood, or timber riddled with nails, this bit combines a self-feeding tip with a dual cutting edge to produce fast, clean holes with minimal effort.
Key Features
- Two-step cutting action for precise, clean holes in wood drilling applications - reduces tear-out and delivers professional-quality results in hardwoods, softwoods, and plywood
- Dura-Tip self-feeding point for extreme durability in nail-embedded wood - the tip pulls the bit forward automatically, reducing operator pressure and fatigue during repetitive drilling
- Dual cutting edge design for effortless, smooth hole drilling in nail-embedded wood - maintains cutting performance even when encountering embedded fasteners
- Deep flutes for fast chip removal - evacuates wood chips rapidly to keep the bit running cool and allow more holes per battery charge in cordless applications
- 7/16 in. hex quick change shank increases stability and durability in cordless and corded impact wrenches and drill drivers - fits standard quick-change chucks for tool-free bit swaps on the job site
Why This Product
- Built specifically for nail-embedded wood - the Dura-Tip and dual cutting edge combination means you can drill through framing lumber with hidden nails without stopping to change bits or risk snapping a standard auger bit
- Deep flutes extend productivity on cordless tools - faster chip evacuation means less heat buildup and more holes before a battery swap, which matters in high-volume framing or plumbing rough-in work
- The 7/16 in. hex quick change shank provides a secure, wobble-free connection in both impact wrenches and drill drivers, so the bit stays on center and delivers consistent hole diameter and alignment
- At 1-1/2 in. diameter with a 5-1/2 in. working length, this bit handles common through-boring tasks in structural framing, pipe and conduit routing, and garden post drilling without requiring an extension
