88714 Speedbor Spade Drill Bit, 7/8 In. X 16 In., Hex Shank

The Irwin 88714 Speedbor spade drill bit is engineered for fast, clean hole boring in solid wood. With a 7/8-inch diameter and 16-inch overall length, this long-shank bit reaches deep into framing, decking, and large carpentry projects where standard bits fall short. The extended shank maximizes reach and stability, delivering superior torque transfer so you drill faster with less effort and less wobble at high speeds.

The blue groove point and cutting edge accelerate chip removal, while double cutting spurs scribe the outside of the hole to reduce breakout and splintering. A sharp split-point tip minimizes the need for pilot holes, saving time and ensuring precise, professional results on every job.
