Built for drilling into wooden utility poles, this impact auger has a wide, reinforced flute for faster chip ejection. The solid single spur leaves a cleaner, smoother hole. This solid carbon steel auger measures 24 inches long, 1 1/4 inches in diameter with a 7/16-inch hex shank. The auger bits are coated with a reinforced anti-friction PTFE coating for overall smoother drilling and easier removal of the bit from the pole.
