Diablo DSP2020 5/16-Inch x 6-Inch SPEEDemon Self-Feeding Spade Bit

The Diablo DSP2020 is a 5/16-inch diameter by 6-inch overall length spade drill bit engineered with a self-feeding SPEED-TIP thread point and an Impact Strong 1/4-inch hex shank for rapid wood boring. Built with an optimized curved paddle geometry that accelerates chip evacuation to extend battery runtime on cordless tools, this high-efficiency wood bit pulls itself through dimensional lumber with minimal operator force. Designed for electricians, plumbers, and framing contractors routing thin wiring lines and installing hardware through wall studs and floor joists, its angled cutting spurs score wood fibers prior to main paddle engagement to prevent entry splinters and exit blowout.

Best Used For:

  • Electrical Wiring & Cable Rough-In: Boring fast, clean 5/16-inch holes through wooden wall studs and ceiling joists for low-voltage wiring and small cable runs.
  • Cabinet & Hardware Fastener Installation: Penetrating floor framing and timber plates to establish clearance holes for lag screws and structural bolts.
  • Structural Framing & Construction Boring: Drilling clean holes through softwoods, hardwoods, plywood, and OSB subfloor panels without stalling high-torque impact drivers.

Key Performance & Safety Features

  • SPEED-TIP Self-Feeding Thread Point: Self-pulling threaded lead screw draws the bit effortlessly through timber to reduce user fatigue.
  • Curved Evacuation Paddle Geometry: Curved paddle profile ejects wood shavings rapidly to eliminate hole clogging and reduce friction heat.
  • Impact Strong Hex Shank Base: Reinforced 1/4-inch hex shank absorbs high torque pulses in impact drivers without snapping or slipping.
  • Angled Scoring Cutters: Precision-ground side spurs score timber surface fibers prior to material removal to ensure clean, blowout-free holes.
  • Cordless Battery Efficiency: Low-friction cutting profile lowers drill motor draw to yield more holes per battery charge cycle.
  • Dual Rotary & Impact Driver Compatibility: Performs with maximum stability in both standard 3/8-inch drill chucks and 1/4-inch hex quick-change impact drivers.
