Quick-change wood auger bit for deep boring through studs, joists, and floor plates -- including nail-embedded wood. The 17-1/2" overall length provides the reach for through-framing work, while the 7/16" hex shank locks into impact drivers and quick-change drill chucks.

• 2-step cutting action: self-feeding lead screw pulls the bit through wood while the cutting edge shears clean, precise holes
• Deep flutes clear chips quickly for sustained speed in long bores
• Built for extreme durability in nail-embedded wood -- well-suited to remodeling, demolition, and rough-in plumbing or electrical
• 7/16" quick-change hex shank fits impact drivers, impact wrenches, and standard quick-change drill chucks
• Diameter: 1-1/16"
• Overall length: 17-1/2"

Tip: Run at moderate speed to keep the lead screw engaged and the chips clearing. On deep bores, back the bit out periodically to clear sawdust and reduce binding.
