88716 Speedbor Spade Wood Bit, 1 In. X 16 In.

The Irwin 88716 Speedbor Spade Wood Bit is a precision-engineered flat wood drill bit designed for boring deep holes in hardwoods and softwoods. At 16 inches long, this extra-long bit reaches far beyond standard bits, allowing you to bore deep holes without changing tools. The flat-flute design delivers smooth entry and clean cutting, while the dual spur geometry ensures professional results in cabinetmaking, joinery, furniture making, and general woodworking projects.

This spade bit solves common drilling problems: tearout and splintering that compromise wood quality, bit slipping and wobbling during operation, and the need to switch between multiple tools for deep-hole applications. The hex shank and grooved design lock securely in any standard drill chuck and quick-change chuck, eliminating slip and rotation during demanding work.

Features and Benefits
