This 8 Inch Auger is also great for digging post holes or for planting several bulbs into a single hole. This model was recently upgraded with our virtually indestructible and replaceable heavy-duty tip. This large garden auger measures 8 inches in diameter by 28 inches long, designed with a heavy-duty, 1.25-inch center shaft made entirely from steel, 12 inches of rugged, 10-gauge double flighting, and a glossy black paint finish.
