Gallon Pot & Post Hole Auger (7″ x 28″)

Our Post Hole Auger is a professional landscaper’s go-to choice when planting gallon potted plants or shrubs. It’s perfect for 4 x 4 fence post hole digging, too. The auger is designed to leave room for cement around the post when digging holes. This heavy-duty auger features a 1.25-inch shaft made from 100 percent steel. Choose the HTD option for replaceable parts and better initial ground penetration. *Drill sold separately.

The Perfect Auger for Digging Post & Gallon Pot Holes

This auger measures 28 inches long and has a 7-inch diameter. The post digger features a 1.25-inch shaft made from 100% steel and double 10-gauge flighting.

We recommend using a gas powerhead with this post auger – but you can also use a large electric drill with a side handle. Look no further for a drill for your new auger. Our 60v drill bundle provides the power you need PLUS a battery and box – available only from Power Planter!

Our Gallon Pot & Post Hole Augers Are Versatile

The tube drive with a heavy-duty tip (THD) is the most rugged and versatile option for this auger. Use the dropdown menu above to choose the “THD” option. The heavy duty digging tip is a replaceable auger tip that will help you tackle the most challenging digging tasks without damaging the main auger. The leading portion of the digging tip has replaceable auger blades (included with purchase). This allows for an easier and more cost-efficient way to keep your equipment performing in top condition for decades.

About Tube Drives

The tube drive auger can fit various drills or powerheads. It will fit any 1/2-inch drill chuck – or larger drill chucks – with the use of the hex adapter included with this purchase. In addition, the auger bit will fit any drill with a threaded end when purchased with a threaded adapter (sold separately). Our adaptable tube drive augers feature 2 holes with pins for mounting and will fit auger powerheads with a 3/4-inch shaft. This is a smart option for professional landscaping businesses who need to switch between drills and powerheads throughout the day. See graphics below for more details.
