Wood Owl Nail Chipper Wood Cutting Auger Bits feature a patented Tri-Cut head design with 3 precision ground cutting edges and chip relieving flutes for optimum performance when cutting wood and nail-embedded wood. The Tri-Cut head balances the bit as it cuts and minimizes kick-back as it reduces wood embedded nails into chips. The precision-cut lead screw pulls the bit straight into and through the material without wandering. The induction hardened high carbon steel construction allows for a long-lasting highly durable bit that on average weighs 25%-30% less than standard steel auger bits, helping to reduce operator fatigue. They feature a quick change 7/16" Hex Shank that can be used with standard 1/2" chucked drills or in specialty Impact Wrenches with QC chucks.
