Irwin (928) 47308 IRWIN® POWER DRILL LONG SHIP AUGER BIT, 17" X 1/2"

Irwin Power Drill Long Ship Auger Bits have single cutter and side lips designed to effortlessly bore holes in wood where nails may be encountered, and cuts through nails without damaging the bit. Shank size: 5/16" hex. Overall length: 17". Twist length: 12". The full-length heat treated bit guards against bending in heavy-duty applications and strengthens the twist where the greatest strain occurs, while the wide lands help keep the bit straight as it bores. The hollow center flutes clear chips quickly out of holes, while the medium-fast screw point is ideal for general woodboring applications.
