  • Sturdy and near perfect for planting a garden
Size: 4"x16"
If you garden, you need a tool like this. Very sturdy piece of gear. It worked great planting tomatoes and peppers in my garden, although, I wish I had bought a longer version that's around three feet long. I wouldn't have had to bend over so much. That said, the tool is tough and held up to some fairly rocky tilled but compacted garden soil. My wife was impressed. Normally I have to use a slim shovel and dig over 100 holes and end up with a backache, no more of that. I was able to stay way ahead of her as she planted. Her comment was she had trouble keeping up with me. The key to making nice holes is to drill it in small bursts and pull the dirt up with the auger, then a quick tap on the trigger to dislodge the dirt. If you run it constantly, it throws dirt all over and becomes a little unwieldy. Also, you end up having too much dirt drop back in the hole, you don't want that. You'll figure it out after a couple of holes. I do recommend using a 1/2" chuck brushless cordless hammer drill. The key is brushless as they stay cool under heavy use. You don't need the hammer part, but 1/2" hammer drills usually have extra torque which is really helpful and they usually have a side handle which is good for stability. I killed my old B&D 3/8" cordless drill. It wasn't made for that, and started smoking after just a few holes. I switched to a 18v Ryobi 1/2" brushless cordless drill (any brand will do though), and it never even got warm. So this auger is great tool and sold at a fair price. It's definitely worth having. ... show more

  • Works!
Size: 4"x12"
This thing WORKS!! Best tool I have ever used to plant seedlings! So much easier than a hand trowel. Yes, you must have a drill, which most should have, and that is it. Put holes anywhere you wish in seconds. Hold drill firmly and adjust speed accordingly, raising bit in and out of hole to clear the dirt from hole. It's that simple and quick. Buy one and you will agree! The 4" x 12" bit is perfect! Plant your seedlings and reap the benefits of your own garden! ... show more

  • Does not work for bigger holes
Size: 4"x12"
We moved and have been buying shrubs and small trees for our lawn so I thought this would help my husband without doing so much hand shoveling. It did not nor was it suppose to. The blade is not sharp. Will work great for planting flowers in landscaping which will use next spring.

  • Perfect option for a lot of holes
Size: 4"x16"
Loved it! Needed post holes for 4x4 posts and this did the trick nicely and quickly. I am a 60 year old woman and did not want to deal with post hole diggers. I don't have the force to make quick progress. Nor was it a big enough job to rent an auger. Those would probably be too heavy for me anyway. This works great. If you have roots or rocks or really hard clay it might take a little longer to stop and get the obstruction out but all in all if you have a bunch of holes to dig I recommend. I was using a smaller one to put in my posts that worked but this size was less work. I used an old Ryobi 18v drill I have. ... show more

  • One honest review
Size: 4"x12"
Works as described but........I have very hard soil and the shaft that goes into the drill strips out. It would be better if it actually had a hex shaft, or a quick release shaft, something for the drill to grab onto.

  • Made planting bulbs a whiz
Size: 4"x12"
Sure made planting flower bulbs easy!!! I used my cordless drill which this attached to quickly. Holes were almost instant for the glad bulbs. After trying this, I look back at the years digging with the small spade to plant the bulbs with a lot of regret. Highly recommend
