40V HP Brushless 8" Auger with 4.0 Ah Battery and Charger
40V HP BRUSHLESS 8" EARTH AUGER KIT is rated 4.8 out of 5 by 388.
Rated 5 out of 5 by from Better than gas I really like my auger. It is heavy enough so it doesn't jump around. It stops if it hits a big rock so just go into reverse and it comes right out.

Rated 4 out of 5 by from Solid Tool for smaller projects The Earth Auger works great for small projects around the property. I used it to install 3 4x4 poles set into 8in concrete tubes for mounting Bat Boxes. The clay would cause the Auger to catch and stop more than I wanted but the anti-kick feature prevented any issues. The power of the tool was okay, its not par with a gas one, so if you plan on doing a full fence or lots of holes in one day I would recommend a Gas Auger or doing it over a few days with this electric one. It was easy to handle and move around.

Rated 5 out of 5 by from Does the job easily! I bought this last fall to dig holes for trees and bushes (20), I didn’t realize that I’m too short, I’m five feet tall on a good day. But I recruited the help of my neighbor, he get the job done and liked using it. Easy to put together and fun to use

Rated 5 out of 5 by from More power than I was expecting I recently put in 35 postholes with a gas powered auger and it was very heavy, hard to control. So a friend had a Ryobi 40v auger and I thought I'd try it out on another fence I was helping with. We drilled 14 post holes, and I was really amazed at the power. I have another few fencing and deck projects coming up this spring so I purchased my own. I am very pleased with its power, and simplicity given that it is electric. Much less weight to drag around from hole to hole.

Rated 5 out of 5 by from Saved a lot of time/effort!! I bought this to aid in the posthole digging for my privacy fence. There was very little kickback, and the handle is padded well so any kickback is cushioned against your hip. The 4ah battery fully charged allowed me to dig 12 36" holes before it needed to be recharged. I was very impressed with the power of the tool. It was a great investment for the cost.

Rated 5 out of 5 by from Easy to use I bought this to dig holes for planting trees at my nursery. The auger is simple to use and like all Ryobi tools a manageable size and weight for women to use. The battery lasted for 30 holes dug one foot deep - through pretty nice soil...it may take more for heavy or dry soils. Overall this tool exceeded my expectations and is a welcome addition to our business!
