Boring Machine Auger Bits, 1/2 in X 8 in

Round shank is designed for use in power drills, drill presses, and boring machines with 1/2" or larger chuck. Full-length heat treated bit guards against bending in heavy-duty applications and strengthens the twist where the greatest strain occurs. Heavy stem increases strength and rigidity while reducing vibration. Shank length is 2". Medium-fast screw point ideal for general woodboring applications.
