5/16IN DUAL AUGER WOOD BIT

Regular price $12.25 $11.00 Sale


The Irwin Spurred Auger (I-100 series) features a clean cutting spur that scribes the hole as the screw point tip pulls it through the wood. Its solid center design increases durability. A full length heat treat strengthens the twist guarding against bending in tough applications.
