Earth drill perfect holes fast and effectively thanks to the tapered design of these Tree Auger Bits. With standard teeth on the outside position and wisdom-style teeth on the inside position, the shape and effectiveness of these bits ensure the perfect drill each and every time. 4′ Standard Length and 2″ Hex Standard Collar.
The tapered design drills holes with a rounded bottom that are ideal for planting trees. For example the 9″ – 18″ bit would drill an 18″ diameter hole that tapers down to 9″ at the bottom of the hole.
