Irwin® Boring Machine Auger Bits feature a round shank and are designed for use in power drills, drill presses, and boring machines with a 1/2" or larger chuck. This full-length, heat treated bit guards against bending in heavy-duty applications and strengthens the twist where the greatest strain occurs. Irwin® Boring Machine Auger Bits are also designed with a heavy stem to increases strength and rigidity while reducing vibration. They have a shank length of 2" and a medium-fast screw point, ideal for general wood boring applications.
