Recommended for use on clean, wooden utility poles, this impact auger has a wide, reinforced flute for faster chip ejection. The single spur design leaves a cleaner, smoother hole. This steel auger measures 30 inches long, 5/8 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.
