Wouldn't use anything else. Own 2.
Nicely made tool. Works great with my “handyman” battery drill. After several holes mostly in Laos but with a hard gravelly bottom, it’s looks almost new. I think it will last a long time.
Works very well, however would like to see the shaft area that fits into the drill be made of hardened steel, as it tends to move in use causing it to bur ending with rounded edges. Which will mean use life will be reduced. These are not cheap and I have a very expensive drill with exceptional power, however with the weight of the powerplanter it makes it difficult for the drill to hold the planter tightly even when fully locked in.
Great little 2 inches augers. We used it to drill 800 holes. The auger doesn't come with a harden steel drill cutting edge and it worn out after first 40 holes. We have to keep weld new harden steel cutting edge all the time to finish 800 holes. Our soil profile range from compacted clay to hard sandy clay and only way to do the job is the whole auger made of harden steel.
Although initially digging great, it did not take long for the carbide tip to wear down to the same porfile as the auger flights. This happened after only about 10 holes. It is stilll digging but requires a fair bit of weight on the auger. I would also reccomend having a less aggressive lead in angle on the carbide tip. This would allow for easier drilling and may help improve tip life. Interchangable tips would be a good idea also.
