Irwin Speedbor Spade Wood Drill Bit

Irwin Speedbor Spade Wood Drill Bit

The Irwin Speedbor Spade Wood Drill Bit is a wood-boring bit series engineered for fast, clean, accurate holes in carpentry, framing, cabinetry, and general construction work. The SPEEDBOR line is available in diameters ranging from 1/4" up to 1-1/2" and overall lengths from 4" to 16", giving pros and DIYers the flexibility to match the bit to the job at hand across the full size range. Every bit in the series builds on IRWIN's original spade bit design with a chamfered cutting edge, an optimized point tip, and IRWIN's patented Blue-Groove cutting edge, combining to deliver up to 2X longer bit life and 2X faster cutting speed than previous IRWIN spade bits. A reinforced shank handles fast rotational speeds and aggressive cutting loads across the size range, and every bit in the family is impact accessible for use in both standard drills and impact drivers.
