I highly recommend getting this auger if you are going to be putting in a new fence or planting perennials in really bad soil like ours which below about 3 inches is almost entirely clay. I used this auger to dig the post holes for a fence around my garden (I got tired of putting in so much work, just to end up most of it going to feed the deer). I live where post holes need to be 3 feet deep to get below the frost line. It is simply not possible to dig this deep with regular pivoting post hole diggers without making the post hole cone shaped with the width of the hole far wider at the top than necessary to allow enough clearance for the handles to get far enough apart to grip the loose soil. As a result you dig out a lot more dirt than necessary. And it requires a lot more concrete, rammed paver base, or expanding foam to set the post than a post hole with the same diameter all of the way down. Using an auger like this one, on the other hand, is amazingly easy with the resulting hole having a constant diameter from top to bottom. No more frustration of trying to pull up the loose dirt as you get deeper only to have it dribble back into the hole because you couldn't get the handles of the post hole digger far enough apart. With this auger you just screw it into the ground until it is full, pull it up and gently tap it sideways to loosen the dirt so it falls out. The dirt stays in the auger because it is being compacted into the cavity as it is drilling down through the soil. However, if the soil is so sandy that it won't pack together, then it maybe difficult to keep the dirt from falling out as you try to raise out of the hole to empty it. However the same would be the case with standard post hole diggers. Wetting the soil before and maybe even while digging might help. This auger is adjustable to dig holes between 4 and 8 inches. The only issue I had is that the post hole for a 4x4 post should really be 10 inches in diameter. This is especially the case when using compacted paver base (aggregate with sharp edge stone from sand up to about 1/2") instead of concrete like I did. With paver base you need to be able to use something with more weight behind it than just a wooden dowel or broom handle, such as a metal bar with a mushroom cap on one end (aka a "wrecking bar") to firmly compact it. If the hole is only 8 inches wide it is very hard if not impossible to have enough room on all sides and especially the corners get a tamper down on all sides. The simple solution is to use the auger to dig out to 8 inches and then using straight blade tool like an ice scraper or your old conventional post hole digger, shave the sides down to increase the diameter to 10 inches. The auger can still be used to pull up this loose soil from the bottom of the hole. I recommend going to about half the depth with the auger, then shaving the sides, then augering the second half and shave the sides rather than going the full depth with just the auger and then shaving the sides back to avoid having to lift all of the dirt from shaving the side the full depth of the hole. The only issues I had with this auger was because of my wet clay soil, the number and size of rocks mixed with the clay and because I was digging post holes where a huge maple had been cut down about 5 years previous. It was harder to get the clay to come out of the auger than it would have been with post hole diggers. But I quickly learned that tapping it on the ground on one side, then turning and tapping it on the other the other side loosened it enough that I could give a good shake and the dirt would fall out. When I would hit a rock larger than about an inch that extended into the wall of hole, I would have to stop and dig it out before I go go on. But that is likely not any different than what would be required with standard post hole diggers. But I would have to stop and cut roots with my sharpened ice scraper that a standard post hole digger would likely have been able to slice through. I have also used this auger to dig holes for a number of perennials like roses and other plants that come in 2 or so gallon pots. This might seem like overkill, but with our high clay soil, it is almost like we are putting these plants in clay pots buried in the ground. The result is that they basically grow in whatever soil we added when planting them. So instead of digging a hole just large enough to fit the pot the plant came in with a little extra around and below it as you would if the basic soil was decent, I dug a much deeper hole than normal and then filled it with good dirt. The roses we planted when I did this are so much healthier and fuller than those we planted before I got this auger.

Perfect tool to dig 4 foot holes from a very cramped crawlspace. I was able to add additional support beams under my cabin in a space that would not have allowed another type of post hole digger. Seams to be overbuilt.

Why did I not know about this thing before?? This simple device is NUTS! It has been phenomenal to use. It is so easy to bore a simple post hole, regardless of soil type. I have HEAVY clay, and boring a simple post hole for a fence is so easy it is nuts. Now, to be fair, if you hit a rock of a root, you are going to struggle, you may need to pull out the borer & hit the rock or root with a heavy digging bar. Turn, dig, pull up & clear the head, repeat. The fact that the shaft is basically a 3/4" black iron pipe with standard NPT pipe threads is a bonus when (if) you decide you need a pipe extension. I am a little nuts, so as someone else posted that he had dug a 30' deep well shaft, I decided to try something similar. As I mentioned I have HEAVY clay, so I wanted to drill a test borehole to see if I could do a dry well. I thought 10' would be enough, it wasn't. I hit super heavy hard sticky clay which is a PAIN to go through, but with steady turns & a constant downward pressure, this thing just gently drills away. My clay was wet, which sounds awful, but it actually digs into it better than dry clay which is like digging into concrete. So I actually ended up digging down 22' in solid clay & didn't hit any sand, so I gave up trying to make myself a dry well, but I am amazed at how strong, how well built & how easy to use this device is. I cannot recommend it highly enough! I have also used it for what it is supposed to be used for & dug post holes too and that simple 2'6" deep hole is EASY & fast to drill, even in my clay. Made setting post holes so much easier. Just don't expect to keep drilling & never pull it up. Drill about 6" & pull it up, clear the head, start again. One piece of advice, regularly check the nut holding the 2 clamshells apart to make sure it is still tight. It will have a tendency to work loose with the constant motion of the head & it would suck to have a deep hole & lose the head. You have been warned.Otherwise, this is a great tool. I did not get paid, reimbursed, of given anything for free (never do as I am not important enough online!) so you are getting my own unbiased, honest opinion & nothing but that. :-)

NPT National Pipe Thread vs NPS National Pipe Straight. Last week I purchased a new Seymour Auger on Amazon to dig a couple new storm drain drywells in the backyard and cleanout alluvial from several preexisting wells. What I didn't expect is that threads on the new AUA2 Tee handle are NOT tapered but straight. It appears that Seymour purposely used straight threads to be used exclusively in conjunction with their SA22035 AU-1AX Auger Extension Coupling Shaft which costs substantially more than purchasing inexpensive standard lengths of 3/4" malleable gas pipe. I tried chasing the tee handle pole threads with a NPT pipe threader die, but discovered that I would have to cut off the end of the pole and cut all new threads. So I secured it in a pipe vise, added a little zoom oil and screwed on a 3/4" coupling with a 24" pipe wrench. What's more, to avoid disappointment before using this Auger in the ground... I strongly recommend taking everything completely apart first, getting familiar with its simple components and reassembling it to your satisfaction! Otherwise it might fall apart unexpectedly and you might have to fish the Auger Bit out of the hole you just dug.

Very loose joins with long blots that torn my clothes and wobbled terribly. One of the spikes fell off at the weld the first time I used it. I’m weak so don’t think it was my muscles that broke the weld. I want to return it but there isn’t a drop off place within an hours drive.
