88818 Speedbor Spade Drill Bit, 1-1/8 In. X 6 In.

The Irwin 88818 Speedbor Spade Drill Bit is a flat-flute wood boring bit designed for drilling in wooden materials. This 1-1/8 inch model features a blue-groove point and cutting edge for faster chip removal. Double cutting spurs scribe the outside of the hole, reducing breakout and tear-out at the hole exit.

The grooved hex shank prevents slipping in the drill chuck or bit extension while fitting all standard quick-change chucks for easy bit changes. The specialized flat flute design includes a scoop geometry that prevents chip and dust buildup during deeper cuts, maintaining consistent performance throughout the drilling task.
