The Irwin Tools 42413- 13/16-Inch Short Ship Auger with Single cutter and side lip is designed to bore holes in wood where nails may be encountered. Cuts through nails without damaging the bit. The hollow center flute clears chips quickly out of the hole. Ideal for applications where chip clogging can be a problem such as with green wood and creosoted poles. The Full-length heat treated bit guards against bending in heavy-duty applications and strengthens the twist where the greatest strain occurs. The Short length allows bit to be used in tight areas and the wide lands keep the bit straight as it bores through the hole. The medium-fast screw point is ideal for general wood boring applications.
