The extension works well and gives you that extra length that you need so that the auger head doesn't get buried in the ground and you don't have to bend over that much.

Reviewed in the United States on January 29, 2024
Size: 12-InchVerified Purchase
I got this extension to be able to drill down about 3 full feet below grade with my Earthquake auger. This extension is a good complement to allow you to reach deeper and obtain the depth that you need. The extension is well made from a quality steel and is painted the same color red as the auger frame.

5.0 out of 5 stars Adds the exact length for getting below frost line
Reviewed in the United States on June 10, 2018
Size: 18-InchVerified Purchase
Perfect fit for an Earthquake auger I recently got that was made in 2004. Adds a little weight to the auger, but then again it also makes the holes the required depth for the getting below frost line in Michigan. Saves a ton of time vs. digging by hand since you can get 18 inches further down with this + the bolt it comes with.

Downfall was the price. Should have been 20$... Not 40$.

4.0 out of 5 stars Simple, but an essential add-on to the Earth Auger to get the depth we needed
Reviewed in Canada on September 28, 2021
Size: 12-InchVerified Purchase
We used the extension and dug about a dozen holes. Worked great for what we needed and for the price we wanted to spend, however, certainly having a full auger extension with blade would be better except it is priced considerably more as well.
