XtremepowerUS 2200W Demolition Electric Jack Hammer Power Drill Concrete Breaker Bar Point & Chisel Bits Chisel Set

Absolutely a Bargain! I have been using this jack hammer for close to a year on various projects at home--breaking up an asphalt driveway, breaking through underground rock, etc. and have never been disappointed. Will it last forever?--probably not, but it should give me several years of dedicated service.The 45 lb. weight is heavy, but manageable. At 73, I can still handle the jack hammer with no problem, but it might not be the case for everyone. The jack hammer comes in a nice heavy-duty case. I ordered three bits for it, but have mainly used the flat 1-ich edge bit.In the fine print of some other reviews, Shell Rotella T1 SAE 40 Heavy Duty Engine Oil was recommended, which I purchased at our local auto parts store. I have yet had to add any oil though. Just keep an eye on the oil level through the small round window.Like most items, a low review is likely due to someone not reading the instructions or not caring for the jack hammer properly. An example: Putting the bit in is tricky, as one has to pull the metal piece on the side of the hammer barrel out and twist 180 degrees in order for the bit to slide in all the way, then pull the small metal piece out again and reverse to the original position. It takes a bit pf practice to master. Once the bit is in, you are good to go. Just watch the oil level. Is the hammer noisy?--Yes, but it is a jack hammer. Be sure to wear your hearing protection.I am thinking of ordering a second of these jack hammers before the prices go up due to the tariffs.

I bought this specifically to break up the bottom of a spa that I intend to fill with dirt. I wasn't sure if it would work, as most of the reviews/videos I've seen are of people breaking up a sidewalk or something, which is definitely not as hard or thick as a pool.Before getting this, I had tried to drill into it and to hit it with a sledgehammer, but the sledgehammer did nothing. I have since read that the bottom of a pool/spa is 8 inches or more, and very hard concrete. As for this tool, when it arrived there was oil leaked all in the case, which was unfortunate. There was no oil in the machine -- maybe that's what leaked out. Strangely though, once I added oil to it and used it, it hasn't leaked into the case again which is a pleasant surprise. The machine feels well built and the two attachments seem very sturdy. I mostly used the chisel bit to break up the bottom of my spa. This size hole took me a good 2 hours, most of the time is just making the initial hole.. once you've hit dirt, you can fairly easily branch out from there. If you're new to jackhammering, watch some videos on it, and don't be tempted to try to stay in one spot and bust through it all at once, the bit will just end up getting stuck. Which happened to me many times, and I just used the other bit to break up the concrete around the stuck bit... so it's a good thing they included 2 bits.All in all this is a great tool, and a great value. I could not have done the job without it. I think it may also be useful in the future for digging in rocky soil.

---Update, July 16, 2019, Three years later---Ok, three years later and here is the take-away… TAKE ONE AND GO! Doesn't use much oil, still on the first fill-up from when it was new (used the recommended oil) and the tank is more than half full. I now have all of the attachments available on Amazon. Each has it's place and works well. Do keep the point sharpened once it dulls out, that makes a difference. Driving fence posts / chainlink fence pipe / grounding rods is great if you can keep the thing balanced during the process. Great for digging in very hard/compact dirt.This is the tool that ends up getting loaned out to friends and neighbors time and time again! Literally, it comes home for a few weeks and then finds it's way out to another DIY project up the street or around the block. Everyone who has used it says "WOW, that was so much better than the other tool (either bigger or smaller) that I was using." Sure I give them a little coaching on where it best fits compared with a larger 60+ lb jack hammer, a plain old sledge hammer (still the right tool in lots of places, like driveway slab removal), and a hammer drill.---Original Review---I ordered this demolition hammer to finish off the removal or a water feature (fountain / pond) in front of my fixer upper after having rented the 60lb Bosch Brute Turbo (~$1700 to purchase, ~$80 rental) the previous weekend. Here are some comparison thoughts for others weighing the rent (a bigger tool) vs buy (a smaller tool) decision.Each option should be considered with a different perspective. For working on a flat slab, the bigger tool has more power, and its own weigh to stand behind it. The moment you start working on uneven surfaces, like the sides of a cement pond, or climbing over rocks of a small waterfall, the small tool is greatly appreciated. Any funny angle surface you start working on with the larger tool and the jack hammer wants to walk its way down, banging your knees as it goes. Practice makes perfect... and leaves bruises.The smaller tool (Xtremepower US 2200...) still has plenty of power for most around the house purposes. It's smaller size and un-even handles are not as ideal as the larger tool when everything it upright, but they are much better the moment you are working on anything that is not flat.In my experience on some sort of very tough concrete (an average slab would have been a piece of cake) the sharpness of the point was more important. The rental tool came with a point which has certainly seen a lot of use and been well beaten down. The sharp point on the end of a fresh bit which came with this hammer was excellent at pounding a small hole, and then splitting pieces apart. I also found that the sharp point changed my plan of attack. With the larger Bosch I spent more time on each location, trying to break off larger chunks to haul off, which were heavy enough that the wife an kids couldn't help toss them in the wheel barrow. With the smaller hammer I aimed at pieces a quarter the size or less and had them breaking off five times as fast. The bonus was that everyone could lend a hand in the clean up.Starting over, I would purchase the smaller tool, and skip the rental for the kind of work I had to do. (Fountain removal, some plumbing rerouting, odds and ends concrete projects.) The place I would go back to a large tool is for lots of flat slab removal. By lots I mean more than 600 square feet and no other projects insight. I do have about 350 square feet of slab removal to do in one location, and another 5-600 square feet in another and am planning to use this tool for it. I'll update this once I get through those in the coming month.I've used the tool for about 5-6 hours now and have not noticed any loose bolts or screws. The oil tank on mine came with about a 1/4 of the tank filled, more than several of the previous reviews mentioned. I do think that I will increase the gauge of the electrical cord, the 16 awg wire it comes with clearly appears under rated for the tool. The bit is designed to float around in the holder. It can get stuck tightly enough that it feels jammed in place. That also seems to hold the bit away from the internal mechanism which strikes it making the machine vibrate but not hammer away. It seemed similar to the behavior some users described. I found that I could lean on the jack hammer and the bit would pop loose and go back to working as intended. I didn't experiment, but a little more oil on the top of the bit may resolve the sticking behavior.--- Update 25 Aug 2016 ---At purchase I also ordered the "TR Industrial TR89102 Clay Spade Scoop Shovel Bit for Electric Demolition Jack Hammer, Silver". It's turned out to be a great help for loosening hard packed soil under stumps so it can be worked out. Easier and faster than using a pick and shovel. The demolition hammer is a bit heavy to use for a lot of scooping, but it's weight is an asset for pounding the shovel in, then leaning it over to loose the soil. Working along a trench or around a stump with someone to follow up scooping the loose material out works well. It's also easy to work shoulder to should since no one had to worry about getting hit by a swinging pick.

Husband used to open basement floor plumbing buildouts. Worked well especially when you break through once. After that spend more time lifting back out. Made multiple small starts.In regards to the oiling seems to oil shaft as necessary. Keep rag around to change shafts. Should be enough oil to last many hours.One piece of advice. Clean away small stuff even the dust can slow you down. Seems to dampen.Would give 5 stars but not convinced of longevity. Only removed about 5 or 6 s\f. Sure beats price to have done when they have time😁

Great product for the price. Will buy it again if I have too.

Works great

Works just as good or better than a rental at home depot
