Diablo Spade Bit DSPD4020 5/8 x 6 Inch Demo Demon (1/4 Hex Shank Self Feed DEMO Edge Dura Tip Nail Embedded Wood Romex Wire Rough In Drilling)

Diablo DSPD4020 5/8-Inch x 6-Inch Demo Demon Self-Feeding Spade Bit

The Diablo DSPD4020 is a 5/8-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 and low-voltage wiring 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 Electrical Rough-In: Sinking clean 5/8-inch holes through older wall studs, floor joists, and subfloors containing hidden framing nails for Romex cable routing.
• Small Plumbing Line & Tubing Pass-Throughs: Penetrating heavy timber plates and stud bays to clear PEX lines and copper piping without bit binding.
• Nail-Embedded Framing Construction: 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 5/8" x 6" Demo Demon™ Spade Bit for Nail-Embedded Wood (DSPD4020)

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.
