Irwin Speedbor Carbon Steel Wood Drilling Bit, Auger Style, 3/4" Bit, 17" Length, 7/16" Shank Size

Ship auger drill bits are long bits that can drill through wood with embedded nails. They create deep holes in timber, pressure-treated lumber, and utility poles. The bits have open spiral flutes and a hollow core that provide efficient chip removal. Each bit has a self-feeding tip that pulls the bit into the workpiece and helps prevent it from moving, or walking, during drilling.
