Diablo Spade Bit DSPD4050 1 x 6 Inch Demo Demon (1/4 Hex Shank Self Feed DEMO Edge Dura Tip Nail Embedded Wood Conduit Boring Drill Bit)

Diablo DSPD4050 1-Inch x 6-Inch Demo Demon Self-Feeding Spade Bit

The Diablo DSPD4050 is a 1-inch diameter by 6-inch overall length Demo Demon spade drill bit engineered with a self-feeding Dura-Tip thread point and an Impact Strong 1/4-inch hex shank for rapid wood boring. Manufactured in Switzerland with high-speed steel and DEMO-Edge dual cutting edges that deliver up to 60X longer life than standard bits, this high-efficiency tool powers through nail-embedded wood without teeth fracturing. Designed for electricians, plumbers, and framing contractors routing electrical cables, PVC conduits, and water lines through remodeled framing or reclaimed timber, its optimized curved paddle geometry clears wood chips rapidly to preserve battery runtime on cordless impact drivers.

Best Used For:

• Remodel & Demolition Rough-In Boring: Sinking clean 1-inch holes through older wall studs, floor joists, and subfloors containing hidden framing nails.
• Plumbing Supply & PVC Conduit Pass-Throughs: Penetrating heavy timber plates and stud bays to clear water piping and electrical conduits without bit binding.
• Nail-Embedded Construction Framing: Drilling high-speed channels through softwoods, hardwoods, plywood, and OSB panels containing embedded steel fasteners.

Key Performance & Safety Features

• 60X Extended Life DEMO-Edge: Ultra-sharp dual cutting edge architecture withstands severe mechanical impact and direct nail strikes in structural timber.
• Dura-Tip Self-Feeding Screw Point: Threaded lead screw pulls the bit through tough wood with minimal user effort while protecting against tip breakage.
• Curved Evacuation Paddle Geometry: Accelerated chip removal channel prevents chip clogging and lowers friction heat buildup.
• Impact Strong Hex Shank Base: Reinforced 1/4-inch hex base resists rotational shearing and chuck slippage in high-torque impact drivers.
• Swiss High-Speed Steel Metallurgy: Premium HSS construction maintains cutting edge sharpness across extreme friction heat applications.
• 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.

• (1) Diablo 1" x 6" Demo Demon™ Spade Bit for Nail-Embedded Wood (DSPD4050)

Technical Specifications

Pro-Tip: Maintain high drill RPMs when contacting embedded framing nails to allow the DEMO-Edge geometry to slice through steel fasteners cleanly without binding or kicking back.
