Diablo Spade Bit DSP1080 1-1/4 Inch x 4 Inch Short Stubby Impact Rated Hex Shank Self-Feeding Wood Boring Drill Attachment Restricted Framing Spaces

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

The Diablo DSP1080 1-1/4-Inch x 4-Inch Stubby Wood Spade Bit is a compact structural boring attachment engineered for high-speed hole-making inside confined wall cavities and restricted framing layouts. Equipped with a threaded SPEED-TIP self-feeding design, this short-profile bit pulls itself through softwoods, hardwoods, and treated timber automatically under minimal axial force to accelerate utility installations. A standardized 1/4-inch hex shank delivers Impact Strong durability inside high-torque drivers, coordinating a proprietary curved paddle geometry for immediate chip clearing with an angled cutting spur that scores clean hole entries to prevent back-side blowout.

Best Used For:

• Confined Space Wiring Rough-In: Bores 1-1/4 inch conduit openings between tightly spaced structural studs where standard long bits cannot physically fit.
• Tight Cavity Plumbing Pass-Throughs: Drills large-diameter piping clearance holes within narrow floor joists, cabinet backs, and restricted utility chaseways.
• Close-Quarter Framing Modifications: Executes clean perpendicular borings across structural wood partitions, joists, and treated structural timbers using compact impact tools.

Key Performance & Safety Features

• SPEED-TIP Self-Feed Threading: Threaded guide lead tip draws the paddle bit into lumber automatically, reducing manual worker fatigue.
• Compact 4-Inch Stubby Length: Minimalist tool body clearance maximizes entry access inside constrained, tight physical construction zones.
• Curved Paddle Material Conveyor: Concave blade face forces out wood fibers instantly to mitigate high frictional heat and prolong motor run time.
• Impact Strong Hex Shank: Hardened 1/4-inch hex connection provides excellent spin stability and resists shear fractures from impact stress loads.
• Angled Spur Scoring Edge: Side spur cutters cut wood grains on the outer edge before the primary lifting edge cuts to prevent rear breakout tearing.

What's Included

• (1) Diablo 1-1/4" x 4" SPEEDemon™ Stubby Wood Spade Bit (DSP1080)

Technical Specifications

Pro-Tip: Align the driver completely straight before triggering the tool; because the 4-inch stubby body responds rapidly to torque spikes in confined bays, maintaining a rigid 90-degree axis ensures clean passage without binding.
