88815 Speedbor Spade Drill Bit, 15/16 In., 6 In. OAL

The Irwin 88815 Speedbor Spade Drill Bit is engineered to drill large-diameter holes quickly and cleanly in wood and soft materials. The distinctive blue-groove point guides the bit and reduces wandering, while double cutting spurs scribe the outside of the hole to minimize breakout and splintering. This bit delivers the speed and precision demanded by both professional contractors and DIY enthusiasts tackling framing, decking, cabinetry, and conduit installation projects.

The Speedbor's innovative design accelerates material removal, slashing drilling time on large-diameter holes while leaving a smooth, professional finish that requires less cleanup and finishing work. The grooved hex shank prevents slipping and fits all standard quick-change chucks, ensuring secure torque transfer during drilling.
