You can also use it as a shovel alternative or garden auger drill bit for planting anything from small vegetables to larger shrubs by reaming out the hole. Our drill is also a great alternative to your gardening hand bulb planter.
  • IDEAL FOR ANY SOIL TYPE: Our patent-pending ground-hole auger bit is effective for drilling into dirt, clay, rocky soil, and sand. This flexible drill bit has been designed to leave a small amount of loose soil in the bottom of a hole to help a new plant start growing and reduce transplant shock.

  • Excellent for soil borings prior to planting flowers
Color: Black
I am a geologist, so this auger was excellent. I tried both a battery-powered drill and a 110-volt drill. Both work OK, but if 110-volts is available, then use a power extension cord. The 110-volt drill has better torque. I was pleased to learn that the soil auger also works in a horizontal position. Was able to shear the hard clayey soil and loosen it up. Previously, I used an 8-inch deep auger, but now realize that the 12-inch deep auger is far better and more versatile. This auger helped to drill a garden hole about two feet wide and two feet diameter. That hard clayey soil was excavated by a soil-scoop, then discarded. The new soil was pea-gravel at the base, then organic potting soil mixed with coarse clean sand. The extra-large hole is then backfilled with the new soil, and the future roots will extend downward where the residual moisture is located. The hexagonal shaft fits into the 3-jaw drill chuck, so there is no slippage while digging into hard soil. This soil auger is strongly recommended. It saves back-breaking work with a shovel and trowel. ... show more

  • Excellent Value, Excellent Product, Drills Right Through Clay
Color: Black
The best digging and gardening product I have purchased. Holes for fence post; holes for small trees, you name it. This product was suggested on Consumer Reports so I thought I would give it a try for my outdoor work and it is awesome. I recommend it to anyone that may have a yard full of clay. It will drill right through the clay...give it a try. ... show more

  • This is a great auger.
Color: Black
If you simply want to know if this auger works or not, I would tell you that this auger works excellent for its intended purpose. If you want more details about this auger, just continue to read on. Due to the pandemic, I spend more time than ever in my house. As I spent more time in my house including the backyard, I found that the backyard is an eyesore to me and my family. Before the pandemic, I worked six days a week and I never really have anytime to go to the backyard. It was pretty much untouched, and weeds overgrew everywhere. Now I have a lot of time everyday, and I decided to work on the backyard to make it look better. Since the backyard never received any maintenance, the soil was as hard as rock. After spending a morning in the backyard, I barely loose any soil and my arms felt sore. I ended up buying this auger after some google search. This auger really makes digging so much easier and it saved my arms. The only down side about this auger is that you need a powerful drill preferable impact drill if your soil is hard like mine. Nevertheless, this auger does a great job in digging and I would recommend it to anyone who need help in digging. ... show more

  • Works Pretty Well, But You Need Arm Strength
Color: Black
I bought this to use as a tiller, because tillers are really expensive, and they are difficult for me to use at times. I didn’t expect this to be perfect for that, and I certainly don’t expect to till acres of ground with this, but I figured I could make do considering this thing costs about a tenth as much as a halfway decent small gas tiller. I just got it yesterday, and I’m liking it pretty well overall. I have it attached to a basic Black & Decker 20V cordless drill. I am using it on the slow speed setting as recommended by the company. However, at the slow speed, it really doesn’t do much, except in soil that is already pretty soft. Even in soft soil, my drill will bog down often and stop spinning. On the fast speed, it does perform quite well. However, I only tried that briefly, as I don’t want to risk breaking my wrist since I don’t have the side handle drill the company recommends. The thing is, the side handle drills I found almost all cost about as much as a small tiller, anyway. And I mean, if I could afford the drill, I would have just bought a small tiller. (I do have a small tiller, but it doesn’t work as well as I’d like for it to.) If you use this thing for what it’s meant for, just digging holes, it works pretty well. It did NOT work well in the hard soil near the side of my house, however in softer soil it worked fine. But don’t expect it to till a small herb bed like I was hoping to use it for. I also suffer from pain in my forearm a lot as a result of an injury a few weeks ago, and this thing is ROUGH on that. Even after 2 minutes of use, my arm is aching quite a bit. I think it takes pretty strong forearms to use this a lot unless you do have one of the side handle drills. ... show more

  • My new favorite garden tool!
Color: Purple
Where do I start? How about with needing to plant 4 fruit trees, 96 stalks of corn, 48 tomato plants, and a couple of blueberry bushes... How did I finish? With this Power Planter drill auger bit. Talk about making fast work out of backbreaking work, this did it for me, and bonus points for being purple! Clearly how fast it works will depend on your drill, but even as my drill was running out of battery, this thing still dug holes way faster and easier than I could. I also used it to just loosen up the soil in the garden, kind of like a giant kitchen mixer. Would recommend highly! ... show more

  • Higher cost, higher quality makes it worth it
Color: Blue
This costs more than others listed on Amazon but it is worth every penny. It is significantly heavier and more sturdy which is exactly what you want to drill through rocky soil like I have. Indeed you get what you pay for.

  • Works amazing Works amazing
Color: Black
This was amazing!! I had to dig extra holes for more support for my house I’m building. The holes that needed to be dug were under the frame and not easy to get to. I tried to hand dig and it took me a whole day to get half a hole dug. I needed to find something so I kept trying to think of a way to dig and then it hit me!!! So I researched and found this auger. Was a bit hesitant that it could get through my hard Georgia soil. Well it did and saved me days of struggle and hard work. My holes we dug pretty quick for having to dig 20 inches down. So happy!!! ... show more

  • Must Have Tool for Penetrating Hard Clay Soil
Color: Black
Excellent for loosening and removing hard clay. I live in an area that has clay beneath the topsoil and when digging holes to plant shrubs, etc., you reach clay withing approximately 5 inches of depth. This auger drill bit is extremely effective in penetrating the clay so you can reach the depth required for planting. The auger bit is made of very strong metal and is as effective as the torque in your drill. The amount of torque or setting on your drill is important. If your drill can handle it, this auger bit can definitely do the job. ... show more
