  • Very useful. Good size and a great price.
Even though I have some doubts regarding how long this bit will last, I have to give it five stars because of its usefulness and price. This bit, on the blade end, is well made and really pulls into the soil quickly. It’s advised to get the blade up to speed and then enter the soil with it very slowly and clear the soil by going in and out in shorter distance until you reach your desired depth. It will pull down fast otherwise and it almost took the drill right out of my hand. It’s a long cutting blade and gives plenty of depth. My concerns are the two piece arrangement of the shaft. The shaft feels a little small in diameter compared to the blade. It is threaded together from two pieces in the middle. I was certain this would probably unthread itself when pulling the bit out of the soil. I was so certain of it that I decided to put some thread locker on it before assembly. It worked great. Just not sure if hitting any rock or heavy root that the thin shaft and connection point will hold up over time. But it’s not meant to be an excavator and putting large holes in soft soil should be no issue for this thing over many years of use. For planting bulbs, this is great. ... show more

  • Does what I want it to do.
Size: 1.6"x16.5"-Green
Perfect size for drilling holes in the yard and garden for filling with compost or vermicompost. Nice and sturdy and makes deep enough holes to get the good stuff where it needs to go. Very handy and happy with the purchase.

  • Easy to use auger digger love it
Size: 1.6"x16.5"+3.5"x16"
As a person that works in the yard all the time, planting bulbs and everything else this came in so handy it works really well. It digs holes to make everything easier to do. I highly recommend it if you’re tired of trying to dig holes with your hands.

  • Great for loosening packed soil in preparation for digging holes.
Size: 1.6"x16.5"
I used the auger with my 3/8” cordless drill for loosening soil to help dig holes for planting shrubs. It worked very well. My soil was hard packed and hard to get into with a shovel. After using the auger I was able to dig holes easily, with no problems at all. Just be careful - if the auger hits a root or rock the drill could twist and wrench your wrist. The auger is holding up well after moderate use. I’m happy that I bought this smallest size rather than one of the larger ones. ... show more

  • Game changer!
Size: 1.6"x9",1.6"x16.5",4"x12",3"x16.5",2"x32"
We moved into a new home a year ago, and the front yard was just... bare. I mean, it was just grass and had no visual appeal. So I came up with a dream - a pretty big one. For reference, I'm 70 and my daughter is 40-something. We cut an interesting shape out of the lawn and built a berm. But with the heat this summer, it's been slow going. Finally, yesterday we had a gorgeous weather day and did the shaping, sprinklering and covering it with landscaping fabric. And then it was time to plant. We tried digging the first hole with a shovel. Too big. We did the 2nd with a hand spade. We broke the handle off of it. 🙄 Then I remembered that I had purchased these augers. Game changer! We got the rest of the 25 plants in the ground in record time. Even the really tough crab grass root network could be overcome! My best advice, after all this... Use both hands when augering. When you encounter tough roots, make a wide circle to find the weakest root and it'll be easier. Don't push too hard! I used a regular Ryobi 18v drill and I'm super thankful that I got them. My daughter was both impressed and relieved, because she bore the brunt of the grunt work. I'm on a fixed income, so I could only afford very young plants. But I believe this garden will be glorious when it matures! ... show more

  • Great tool but needs power
Size: 1.6"x16.5"
Construction is great. Maybe needs a more pointy head so it is easier to get into the soil. Also does not work on hard soil unless you have a real powerful drill. So the soil has to be really soft for this tool to be effective.
