More Info

This large auger model was recently upgraded with our virtually indestructible and replaceable heavy-duty tip for added longevity. 

Tackle the biggest digs with ease.

Big jobs require a big auger, and measuring in at 9 inches in diameter by 28 inches long, this extra-large auger bit fits the bill. It features a rugged, 1.25-inch center shaft made out of 100% steel and 12 inches of double 10-gauge flighting (this doubles digging efficiency compared to single flighting). And, the heavy duty digging tip is a replaceable auger tip that will help you tackle the most challenging digging tasks without damaging the rest of the extra large auger. The leading portion of the 9-inch auger’s digging tip has replaceable auger blades (included with purchase) for a cost-effective solution to maintaining optimal performance for years to come

The 9-inch auger bit comes with an adaptable drive that will fit any 1/2-inch drill chuck – or larger drill chucks – with the use of the hex adapter included with this purchase. The large auger bit will also fit more powerful equipment like Stihl BT45 powerheads when purchased with a threaded adapter (sold separately). Additionally, our Quick Attach Auger Adapter is designed for seamless auger performance with any drill with a 7/16″ Quick Attach Chuck.

We recommend using an auger powerhead or drill with at least 60V of power with this bit – the extra large earth auger will fit any gas powerhead with 1-inch shaft. These products fit ½-in chuckeddrills. Our 60v drill bundle provides the extra large earth auger all the power you need for your projects PLUS TWO bonus batteries and hard carrying case – available only from Power Planter!
