Diablo Spade Bits DSP2150-P2 1-1/4 Inch x 6 Inch (2-Pack Impact Rated Hex Shank Self-Feeding Wood Boring Drill Attachment Electrical Piping Rough-Ins)

High-Speed Wood Boring Attachment Set with Threaded Self-Feeding Tip for High-Torque Impact Drivers

The Diablo DSP2150-P2 1-1/4-Inch x 6-Inch SPEEDemon Spade Bit 2-Pack delivers high-speed structural wood boring when running large-diameter electrical conduits or utility lines through structural framing. Engineered with a threaded SPEED-TIP self-feeding design, these bits act as a lead screw to pull the cutting edge through timber under low axial force, minimizing user fatigue and extending cordless battery runtime. Standardized 1/4-inch hex shanks supply Impact Strong structural integrity inside high-torque impact drivers, deploying a specialized curved paddle configuration for rapid chip clearing paired with angled outer spurs that score smooth entry perimeters to prevent rear material blowout.

Best Used For:

• Large Conduit Wiring Rough-In: Bores 1-1/4 inch structural pathways through nominal wood studs and top plates to route commercial or residential power lines.
• Utility Plumbing Pass-Throughs: Drills high-velocity clearance holes inside structural floor joists and subfloors to clear industrial water lines or waste piping.
• Heavy Framing Structural Alterations: Executes straight, controlled perpendicular cuts into natural hardwoods, softwoods, and thick pressure-treated structural timbers.

Key Performance & Safety Features

• SPEED-TIP Self-Feed Threading: Threaded pilot guide tip draws the bit into wood framing mechanically, eliminating the necessity for heavy physical operator pushing force.
• Curved Paddle Material Conveyor: Concave paddle geometry forces out dense wood fibers instantly, suppressing thermal friction and maximizing driver battery lifespan.
• Impact Strong Hex Shank: Hardened 1/4-inch quick-change hex interface locks securely into impact tooling collets to prevent chuck spinning and rotational shear.
• Angled Spur Scoring Edge: Leading edge side spurs sever wood grains along the outer circumference before core lift occurs, ensuring clean entries with minimized blowout.
• Multi-Platform System Compatibility: Custom-engineered tool geometry achieves peak mechanical efficiency in corded or cordless impact tools and standard drill chuck assemblies.

What's Included

• (2) Diablo 1-1/4" x 6" SPEEDemon™ Wood Spade Bits (DSP2150)

Technical Specifications

Pro-Tip: Allow the threaded tip to draw the spade bit through structural wood profiles at a controlled speed without leaning your full weight into the driver; forcing the drive manually may jam the curved paddle system in sticky sap pockets or dense structural lumber knots.
