Irwin Speedbor Hybrid Drill Bit: 1 1/2 in Drill Bit Size, 1.5 Decimal Equivalent, 2 7/8 in Flute Lg

These drill bits feature three cutting spurs for fast hole drilling with minimal breakout. Hybrid utility drill bits can drill through nails and are commonly used for framing applications. The bits have three open flutes that eject chips efficiently and help prevent the bits from binding during drilling. They also have a self-feeding screw-point tip that pulls them into the workpiece and helps prevent them from moving, or walking, during drilling. Wire-fishing holes near the bits' tip allow wires to be pulled through surfaces after drilling.
