Diablo DSPD4920-S6 Demo Demon 6-Piece Self-Feeding Spade Bit Set

The Diablo DSPD4920-S6 is a 6-piece Demo Demon spade bit set featuring 1/4-inch Impact Strong hex shanks and DEMO-Edge dual cutting edges for boring through nail-embedded wood during demolition and rough-in framing. Manufactured in Switzerland with high-speed steel and self-feeding Dura-Tip lead screws, these 6-inch long bits withstand direct fastener strikes while delivering up to 60X longer life than standard spade bits. Designed for electricians, plumbers, and framing contractors routing pipe and wire conduits through repurposed or salvaged lumber, the set covers 1/2-inch through 1-1/4-inch hole diameters while utilizing an optimized curved paddle design to clear wood chips rapidly and preserve battery runtime on cordless impact drivers.

Best Used For:

  • Demolition & Remodel Rough-In Drilling: Boring fast conduit and wire clearance holes through older stud walls, floor joists, and subfloors containing hidden framing nails.
  • Plumbing Supply & Waste Pipe Pass-Throughs: Sinking 1/2-inch to 1-1/4-inch diameter holes through dimensional timber and double-top plates for PEX lines and PVC drain pipes.
  • High-Torque Framing Fastener Clearance: Drilling clean pass-through channels in hardwoods, softwoods, and structural plywood without snapping bits upon nail impact.

Key Performance & Safety Features

  • 60X Extended Life DEMO-Edge: Dual cutting edge architecture withstands severe mechanical shock 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 tooth fracture.
  • 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.
  • 35% Value Set Bundle: Provides six essential contractor bit sizes in one kit to lower per-bit operational costs on high-volume jobsites.
