The Irwin 88706 Speedbor spade drill bit is a precision wood-boring tool designed for deep, clean holes in timber applications. With a 16-inch overall length, this extra-long bit reaches depths required for structural work, joist drilling, and installations where standard bits fall short. The flat flute design and dual cutting spurs deliver clean, splinter-free holes while minimizing wood tear-out, making it ideal for framing, decking, cabinetry, and any project requiring professional-grade results.

This spade bit combines durability with user-friendly design. The grooved hex shank prevents slipping in drill chucks and fits all standard quick-change chucks, ensuring consistent torque transfer and stable drilling. The double cutting spurs scribe the perimeter of each hole, reducing breakout and keeping your workpiece looking finished without extra cleanup.

Features and Benefits

  • Extended Length: The 16-inch overall length reaches depths needed for deep-set fasteners and structural applications without requiring bit extensions.
  • Flat Flute Design: Creates smooth-sided openings that minimize splintering and wood tear-out for a professional finish.
  • Double Cutting Spurs: Precision-ground spurs scribe the perimeter of each hole, preventing breakout and reducing splinter risk.
  • Grooved Hex Shank: The 1/4-inch grooved hex shank eliminates chuck slippage and fits all standard quick-change chucks for reliable power transfer.
