The Perfect Auger for Digging Post & Gallon Pot Holes

The gallon pot & post hole auger measures 28 inches long and has a 7-inch diameter. It features a 1.25-inch shaft made from 100% steel and double 10-gauge flighting, giving it more than enough strength and durability to withstand tough jobs in the dirt, while digging twice in a single rotation of the auger.

We recommend using a 60V cordless drill with this 7-inch auger – but you can also use a Stihl BT45 in conjunction with our threaded adapter. Never use an impact driver with an auger. Need a drill? Shop 60V cordless drills and augers. New to augers? Watch Getting Started with Digging Augers.
