Diablo DSP1070 1-1/8-Inch x 4-Inch SPEEDemon™ Spade Bit

The Diablo DSP1070 is a 1-1/8-inch diameter by 4-inch stubby length SPEEDemon™ spade bit engineered to bore rapid clearance holes through hardwoods, softwoods, and plywood during rough-in framing and tight-space utility installations. Constructed with a threaded SPEED-TIP™ self-feed point, this high-production wood-drilling tool aggressively pulls itself through timber to minimize physical operator feed effort. Featuring an optimized curved paddle profile for rapid waste evacuation and an Impact Strong™ 1/4-inch hex shank, it integrates directly with high-torque corded and cordless impact drivers to deliver clean entry and exit holes while maximizing battery run-time efficiency.

Best Used For:

  • Plumbing & Electrical Rough-In Routing: Drilling 1-1/8-inch clearance passages through floor joists, top plates, and wall studs for water lines, conduit runs, and heavy wire bundles.
  • Tight-Space Structural Framing Work: Operating in cramped stud bays, corner framing junctions, and joist cavities where standard 6-inch spade bits cannot fit.
  • High-Speed Battery-Powered Wood Drilling: Clearing wood chips rapidly during continuous hole-making passes to prevent motor drag and maximize holes per battery charge.

Key Performance & Safety Features

  • SPEED-TIP™ Self-Feed Point: Threaded pilot tip pulls the bit through timber automatically to accelerate hole production with minimal user push force.
  • Optimized Curved Paddle Geometry: High-volume curved paddle design ejects wood chips continuously to prevent binding, friction heat, and motor stalling.
  • Impact Strong™ 1/4-Inch Hex Shank: Solid steel hex shank resists high rotational torque shear to ensure long durability in power impact drivers.
  • Angled Spur Cutting Edge: Precision perimeter spur scores wood fibers cleanly prior to main waste removal to eliminate tear-out and exit blowout.
  • Compact 4-Inch Stubby Length: Short-profile assembly length provides optimal maneuverability inside confined stud bays and tight jobsite quarters.
