40V HP Brushless 8" Auger with 4.0 Ah Battery and Charger
40V HP 8" Brushless Auger with 4.0 Ah Battery and Charger is rated 4.7 out of 5 by 37.
Rated 3 out of 5 by from Decent homeowner / light agricultural tool I bought this to dig some holes in slightly rocky / clay soil at home and for the same purpose at some country acreage (clay) It worked well in rocky soil except when encountering larger rocks (as I expected) The anti kickback mechanism was "ok". It "might" have worked when I hit a root but my hand did get jarred first and I released the trigger. It didn't feel like there was enough anti-kickback in play. Power switch feels flimsy. They should have designed something more rugged. Apart from that, it made short work of hole digging. Beats working with a shovel / pick / post hole digger for hours.

Rated 5 out of 5 by from Powerful enough I have fairly hard compact clay laced with rocks. I was able to dig a 1.5'x8" hole in about 45 seconds. I'm still learning techniques to get around the rocks, but it makes pretty easy work for digging holes. My came with a free quick charger, but I can dig many holes before it needs to be charged. With the quick charger (~1 hour) I see no delay in projects. An hour is barely enough time to put the posts in and let them set before I need to dig more. I've only had it for a few days and it was hard to get a hold of one. So far Ryobi/Homedepot have had great support for their products and I'm not worried about the long term with anything I get from them.

Rated 5 out of 5 by from Surprised with the Power! I needed to set 10 posts and never used any sort of gas or electric auger before. Alway did it the old fashion way, post hole digger. The area I live has hard pan about 6” to 10” down so I was indecisive what to buy, gas or electric. Fortunately the local Home Depot on had this little gem. I had my doubts about a battery operated auger and ensured if it didn’t perform as indicated on the packaging I could return it without any issues. Well, it’s a keeper. I cut the 2’ deep holes with minimal effort and on a single charge. Now, the ground is damp and I’m pretty certain I’d have difficulty during the hot dry summer when the soil is like concrete but it would be difficult with any type auger. I’m very impressed and would recommend to my friends.

Rated 5 out of 5 by from Works great as an Ice Auger I bought this intending to use it as an ice auger in the winter and earth auger in the summer. Because the unit runs in reverse, I was able to use my Jiffy auger blade on the ice. Had no problem drilling through 1 foot thick ice. After 5 holes the 4 amp hour battery still had 50% power. This is a heavy duty unit that I would highly recommend.

Rated 5 out of 5 by from Like All Ryobi Tools It Works Great Like All Ryobi Tools It Works Great The Ryobi Auger Works great just what I needed for my raised gardens and flowers it saved my back a lot aches. It fits in with all my other Ryobi 18 volt tools. The ONE HP brushless motor is very strong and the 4AH battery lasts.This came with the new stye battery and charger The battery has a charge test button great to check before using . This 6’’ Auger is 50% lighter than the average gas unit. It has forward and reverse plus the anti-kickback system is a great safety feature. Quick connect allows easy bit change. This makes my yard/garden work a lot easier from digging holes for bird houses posts/compost tilling to tilling the raised gardens soil packed from the winter snows and it is backed by a 3 year warranty,a win for all

Rated 4 out of 5 by from Plenty of Power! Bought this for both yard work (post holes and tree planting) and ice fishing. LOTS of power for any hole digging! It is really a 5 star tool but the blades were so dull and coated with paint that I had to remove them, sharpen, and strip the heavy paint. The point of the auger also needed to be sharpened, especially for use in ice drilling. Definitely recommended.

Rated 5 out of 5 by from Surpring power I'm not much of a Ryobi user and honestly I bought this tool thinking I might have to return it. But after one week of using it I'm impressed. The power is on par with a gas auger, it's extremely easy to use, and very durable. I dug several 32" deep holes with relative ease. I do still use a 2 handed post hole digger to extract the dirt, and I'm looking for a bit extension so I don't have to take the auger to the ground for our frost line requirements here. But it worked great battery life exceeded my expectations. Good job Ryobi. Only complaint is the anti-kickback is not that effective.

Rated 5 out of 5 by from 40V HP 8" Brushless Auger with 4.0 Ah Battery The RYOBI 40-VOLT HP LITHIUM-ION CORDLESS EARTH AUGER WITH 8 IN. BIT AND 4.0 AH BATTERY AND CHARGER INCLUDED is an impressive little beast. It arrived well packaged and in good time. Let me start with the only negative I could find, the charger plug where it plugs in, the prongs were a little bit crooked in the plastic from the manufacturer. I had to rebend the blades to be able to plug in the charger. Assembly was easy and we took it out for a test run drilling into wet heavy clay ground. It preformed flawlessly, we drilled a 30 inch hole in less than a minute. Try doing that with a standard two handled post hole digger. No way could you do that by hand so fast. It loaded down a little bit, but did not bog down in the wet sticky clay. Time will tell how it handles when we get into rocks and roots. Good job guys, my son was impressed. One more good tool to put to use.
