Diablo Auger Drill Bit DAG1120 15/16 Inch Wood Boring Tool (7 1/2 Inch Length 7/16 Hex Shank Dura-Tip Dual Edge Nail-Embedded Clean Hole Boring)

Diablo DAG1120 15/16" x 7.5" Dura-Tip Self-Feed Nail-Embedded Wood Auger Drill Bit

The Diablo DAG1120 15/16-inch wood auger drill bit bores through nail-embedded framing timber, drills clean pass-through runs for electrical conduit and PEX water lines, penetrates dense hardwood joists, and powers through reclaimed lumber without binding. Measuring 7.5 inches in total length with an impact-rated 7/16-inch power hex shank, this high-speed steel boring accessory incorporates a self-feeding threaded Dura-Tip point and dual cutting edges to slice smoothly through hidden steel fasteners without stalling. Featuring a two-step cutting action that eliminates exit blowout, deep-fluted geometry optimized for rapid chip ejection and extended cordless battery runtime, and premium Swiss manufacturing, it provides residential electricians, plumbers, and framing contractors with fast, burr-free boring performance across demanding jobsite framing assemblies.

Best Used For:

• Electrical Rough-In and Utility Routing: Boring 15/16-inch clean diameter holes through wall studs, floor joists, and double top plates to run standard 1/2" and 3/4" electrical conduit or Romex bundles.
• Plumbing Supply Line Installation: Drilling precise, chatter-free pass-through channels in multi-ply timber headers and structural beams for 1/2-inch and 3/4-inch PEX and copper water lines.
• Nail-Embedded Timber and Remodeling Framing: Penetrating old-growth lumber, reclaimed structural beams, and subfloor assemblies containing embedded steel framing nails without tip fracture.

Key Performance & Safety Features

• Self-Feeding Dura-Tip™ Point: Threaded lead screw tip pulls the bit through wet or dry lumber automatically, eliminating feed pressure while chewing directly through embedded nails.
• Dual Precision Cutting Edges: Balanced twin cutting spurs score wood fibers ahead of the main cutter to deliver clean entry and exit holes without splintering or tearout.
• Two-Step Cutting Geometry: Progressive cutting profile reduces rotational torque resistance, significantly decreasing motor strain on cordless tools for more holes per battery charge.
• Deep Chip Evacuation Flutes: Wide, polished spiral flutes channel moist wood shavings rapidly out of deep holes to prevent chip packing, friction heat, and bit bogging.
• 7/16-Inch Quick-Change Hex Shank: Heavy-duty power hex shank provides non-slip chuck grip and locks securely into 7/16" quick-change adapters, drill chucks, and high-torque impact tools.
• High-Speed Steel Construction: Premium heat-treated tool metallurgy engineered to withstand high torsional shock loads and high-speed rotary impact forces.

Technical Specifications

Pro-Tip: When boring through multi-stud framing plates with a high-torque right-angle drill, keep the tool perpendicular and allow the Dura-Tip lead screw to pull the bit naturally at moderate RPM; avoiding excessive pushing lets the dual cutting edges slice nails cleanly without binding in deep wood flutes.
