Diablo Spade Bit Set DSP2920-S6 6 Piece SPEEDemon (1/4 Inch Hex Impact Shank Self Feeding Speed Tip High Carbon Steel 3/8 to 1 Inch Wood Drilling)

Diablo DSP2920-S6 SPEEDemon 6 Piece High Carbon Steel Spade Bit Set

The Diablo DSP2920-S6 is a 6-piece high carbon steel spade bit set engineered to bore rapid, burr-free clearance openings ranging from 3/8-inch to 1-inch diameter through softwoods, hardwoods, plywood, and clean lumber. Featuring the self-feeding SPEED-TIP™ lead screw and a curved paddle geometry, these 6-inch long wood-boring bits automatically draw themselves through structural framing to accelerate chip evacuation and reduce motor friction. Equipped with 1/4-inch hex Impact Strong™ shanks and angled spur cutting edges, this drill set mounts securely into cordless impact drivers and drill chucks to prevent slippage during high-speed electrical wiring and plumbing rough-in operations.

Best Used For:

• Electrical Wiring & Cable Rough-In Framing: Boring clean 3/8-inch to 1-inch clearance holes through 2x4 framing studs, floor joists, and wall plates for Romex cables and conduit.
• Plumbing PEX & Pipe Pass-Throughs: Slicing accurate openings through softwood and hardwood framing assemblies to route PEX supply lines and small copper tubing.
• General Carpentry & Wood Working: Executing fast, burr-free holes in plywood panels, particle board, and softwoods with minimal exit blowout.

Key Performance & Safety Features

• Self-Feeding SPEED-TIP™ Lead Screw: Threaded tip design pulls the bit smoothly through wood substrates to maximize drilling speed with minimal feed force.
• Curved Paddle Chip Evacuation: Optimized curved paddle design clears wood shavings rapidly from the hole to prevent bit binding and increase holes per battery charge.
• Angled Spur Cutting Edges: Precision-ground spurs score the wood fibers prior to main paddle contact to eliminate edge splintering and top-side blowout.
• 1/4-Inch Hex Impact Strong™ Shank: Hardened hex shank absorbs high torque stress from impact drivers and prevents chuck slippage in standard drills.
• High Carbon Steel Construction: Premium high carbon steel alloy delivers extended cutting edge sharpness and thermal stability during repeated drilling passes.
• Comprehensive Size Selection: Includes six essential contractor bit sizes from 3/8-inch to 1-inch for versatile jobsite utility.
