Diablo Spade Bit DSP2140 1 1/8 x 6 Inch SPEEDemon (1/4 Hex Shank SPEED TIP Self Feed Curved Paddle Timber Plumbing Wire Rough In Wood Boring)

Diablo DSP2140 1-1/8-Inch x 6-Inch SPEEDemon Self-Feeding Spade Bit

The Diablo DSP2140 is a 1-1/8-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. Featuring 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 large drain lines, conduit, and electrical wiring 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:

• Plumbing Drain Line & Conduit Rough-In: Boring fast, clean 1-1/8-inch holes through wooden wall studs and floor joists for PVC waste lines, copper pipes, and heavy conduits.
• Electrical Cable & Bundle Pass-Throughs: Penetrating heavy timber framing and wood plates to clear large bundled electrical cables and flexible conduit runs.
• Structural Framing & Construction: 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.
