Diablo Spade Bit DAG3060 11/16 Inch x 17-1/2 Inch Single Pack 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 DAG3060 11/16-Inch x 17-1/2-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 Dura-Tip self-feeding design, this quick-change bit pulls itself through softwoods, hardwoods, and nail-embedded timber automatically under low axial force to diminish user fatigue during deep framing installations. A standardized 7/16-inch hex shank delivers structural stability inside high-torque impact wrenches, coordinating a proprietary dual cutting edge geometry for immediate chip clearing with an angled cutting spur that scores clean hole entries to prevent back-side blowout over a 13-1/2 inch maximum boring depth.

Best Used For:

• Deep Cavity Wiring Rough-In: Bores 11/16-inch pathways through multiple consecutive structural wood studs or deep wall cavities to route electrical lines.
• Stacked Framing Pass-Throughs: Drills high-velocity clean openings through double top plates, thick structural joists, and layered subfloors to run line components.
• Nail-Embedded Wood Boring: Leverages a hardened high-speed steel matrix to punch precise straight holes through heavy framing lumber containing hidden structural nails.

Key Performance & Safety Features

• Dura-Tip Self-Feed Points: Threaded guide lead tip draws the bit into lumber automatically, dropping the manual push pressure needed.
• Two-Step Cutting Action: Dual cutter geometry scores and clears material sequentially for clean holes and minimal surface breakout.
• Extended 17-1/2 Inch Reach: Long structural shaft provides the clearance necessary to drill through deep cavities and thick timber beams.
• 7/16-Inch Quick-Change Shank: Heavy-duty industrial hex shank prevents spinning in large chucks and interfaces directly with high-torque impact wrenches.
• High-Speed Evacuation Flutes: Deep flute tracks act as a continuous mechanical conveyor to pull out chips instantly and suppress thermal friction.

What's Included

• (1) Diablo 11/16" x 17-1/2" Dura-Tip™ Auger Bit (DAG3060)

Technical Specifications

Pro-Tip: Maintain a straight drilling angle over the full 17-1/2 inch extension and let the threaded self-feeding tip draw the auger bit through timber at a steady pace; backing the tool out slightly on deep runs clears dust pathways and keeps the dual cutting edges working efficiently.
