Diablo Spade Bit DSP3020 1/2 Inch x 16 Inch Extended Reach Impact Rated Hex Shank Self-Feeding SPEED-TIP Wood Boring Drill Attachment Framing Studs

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

The Diablo DSP3020 1/2-Inch x 16-Inch Extended Length Wood Spade Bit is a deep-reach boring attachment engineered for drilling rapid utility openings and structural pathways through deep wall cavities and stacked lumber. Equipped with a threaded SPEED-TIP self-feeding design, this quick-change bit pulls itself through softwoods, hardwoods, and treated timber automatically under low axial force to diminish user fatigue during deep framing installations. A standardized 1/4-inch hex shank delivers Impact Strong structural 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 over a 14-inch maximum boring depth.

Best Used For:

• Deep Cavity Wiring Rough-In: Bores 1/2-inch pathways through multiple consecutive structural wood studs or deep wall cavities to route cabling.
• Stacked Framing Pass-Throughs: Drills high-velocity clean openings through double top plates, thick structural joists, and layered subfloors to run line components.
• Extended Structural Timber Boring: Leverages a 16-inch overall reach to punch precise straight holes through heavy-duty treated exterior posts and structural wood compositions.

Key Performance & Safety Features

• SPEED-TIP Self-Feed Points: Threaded guide lead tip draws the bit into lumber automatically, dropping the manual push pressure needed.
• Extended 16-Inch Steel Reach: Long structural shaft provides the clearance necessary to drill through deep cavities and thick timber beams.
• Curved Paddle Geometry: Deep concave blade configuration forces wood fibers out instantly to reduce thermal buildup and maximize tool battery 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 1/2" x 16" SPEEDemon™ Extended Wood Spade Bit (DSP3020)

Technical Specifications

Pro-Tip: Maintain a straight drilling angle over the full 16-inch extension and let the threaded self-feeding tip draw the spade bit through structural wood at a steady rate; forcing or tilting the tool can bind the long steel shank inside deep timber joists.
