Diablo DAG1110 7/8 Inch x 7-1/2 Inch Dura-Tip Wood Auger Bit

The Diablo DAG1110 is a 7/8-inch diameter by 7-1/2-inch overall length high-speed steel auger bit engineered to bore continuous utility pass-throughs in heavy timber, softwoods, hardwoods, plywood, and nail-embedded wood. Built with a self-feeding Dura-Tip™ threaded lead screw and a dual-edge cutting head, this wood-boring tool pulls itself through structural framing studs and joists while slicing through embedded steel fasteners without binding. Featuring a 5-1/2-inch working length with extra-deep chip evacuation flutes and a 7/16-inch quick-change hex shank, it integrates directly with high-torque impact wrenches and 1/2-inch drill chucks to maximize battery runtime and drilling speed during rough-in electrical wiring and plumbing installations.

Best Used For:

  • Electrical Wiring & Cable Rough-In Framing: Boring precise 7/8-inch clearance openings through 2x4 framing studs, top plates, and floor joists for Romex cable runs and low-voltage conduits.
  • Nail-Embedded Timber Construction: Slicing cleanly through reclaimed timber, subfloors, and framing lumber packed with embedded construction nails, staples, and screws.
  • Structural Timber & Post Drilling: Executing 5-1/2-inch working depth bores through solid structural beams, pressure-treated posts, and engineered wooden assemblies.

Key Performance & Safety Features

  • Self-Feeding Dura-Tip™ Screw Head: Aggressive threaded lead screw pulls the bit smoothly through wood substrates with minimal operator push effort.
  • Dual Cutting Edge Tooth Geometry: Two-step shearing edge formulation cuts cleanly through wood fibers and embedded nails while extending cutter life.
  • Extra-Deep Chip Evacuation Flutes: Oversized flute clearance channels clear wood shavings quickly to prevent binding, lower torque friction, and increase holes per battery charge.
  • 7/16-Inch Quick-Change Hex Shank: Heavy-duty hex shank prevents chuck slippage and ensures secure lock-in fitment in high-torque impact wrenches and 1/2-inch drill chucks.
  • High-Speed Steel Body Construction: Hardened alloy core resists thermal expansion and snapping during high-stress structural drilling applications.
  • 5-1/2-Inch Deep Working Reach: Compact 7-1/2-inch overall length provides maneuverability between standard stud bays and tight framing spaces.
