88706 Speedbor Spade Drill Bit, 3/8 X 16 In.

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.
