ARKSEN 2200 watts Demolition Electric Jack Hammer w/ 1-1/8" Hex Spade Shovel Bit

Chews through concrete like butter, the added attachments were nice, I did some research and this one seemed to have the highest power and the most attachments for the lowest price, compared to the competition. The case as other reviewers have noted is cracked and appears to be the same grade of plastic dodge used for its dashes in its pickup trucks that were notorious for cracking, so that was fairly useless. Other than that it performed great, didn't come with oil, but that's the only drawback I've seen, the seller on Amazon followed up after purchase also which was nice.

This is Chinese knock off crap. If you want a quality hammer go with the Hitachi they stole the design from. Since I don't use it all that much it is fine for me and I don't mind taking it apart to adjust the hammer, or put new seals on it. Doesn't have really consistent hammering and it gets hot while under heavy use, but since I only use it about 15 minutes straight before I need to shovel and do over things, it works. I wouldn't even think of using this for a really large or really heavy duty task. The bits are every much as cheap as the unit itself. My chisel bit broke the first week, so I had to rig up a hack to keep it working. So as much as I complain about the quality (which is extremely poor), the price was right and I have been able to use it in my trenches for the past couple years. I just know I have to baby it and be patient as it isn't going to perform like the much more expensive higher quality hammers.

First, if you get this jackhammer, you will want to get the the following:- Shell Rotella T1 SAE 40 weight oil. (Not 10W40, etc., just straight 40 weight)- 10 awg extension cord (especially for 50' or 100')The oil was harder to get, as most places wanted to sell 3 gal. All you need is a quart. I was able to order it at Napa and O'Reilly auto parts stores. May 2017 it was $6-7/qt or $20/gal.You can check the pictures, I used it on 10 posts to remove the concrete from the metal posts. It worked just fine and the bit penetrated as I would expect. It took me less than 1.5 hrs to do them all. I used a 100 foot, 10 gauge extension cord. The unit does get hot, so be careful touching the sides.I haven't used a jackhammer before and it took a few minutes to get the rhythm right. It is distinctly different when it is 'breaking' and when it's not. I found that when it wasn't 'breaking, just restarting brought it back. Also, it may not contact as well at first because it's not lubricated. Just keep at it until the oil gets into the bit. It might help to pre-oil the top of the bit and the socket. After that, it was just a matter of hanging on while it went through the concrete.Once started, the bit gets stuck in the rock. At that point, it's just a matter of endurance until the concrete cracks. You'll know your close when small cracks start to appear. You will want a dust mask because it occasionally puts out clouds of rock dust. (The mask that comes with it is cheap, I recommend getting a better on.)The jackhammer comes with a case (with wheels), padded gloves, ear plugs, safety glasses, dust mask and tools. (See picture)At first, I thought the gloves were just the cheap work gloves, but they are padded and worked well with the hammer. I plan on using them only with it.Overall, I am very pleased with it. I'm sure an $800 hammer would have advantages, but for the price, it will be cheaper than renting one - especially for small projects now and in the future.

I bought this one to replace a lower powered but similar TR jack hammer (after many hours of hard use). My new Arksen is noticeably more powerful than the TR was and is also a much more refined tool in terms of its finish and grip comfort. The grip is sturdy but mine broke because I let the Arksen slide onto a rock accidentally (an epoxy fix). The TR handle was all steel and probably much tougher. I noticed a few drips of oil at the base of bit when working the Arksen hard but that probably shows its lubrication system is working well. So far my Arksen has held together well while I had to re-tighten many screws on the TR after some early use. I was able to break hard limestone much more easily with the Arksen compared to TR. I am using an extension cord with 10 gauge wiring (15 amp plugs) to handle the extra amps pulled by the Arksen. So far the Arksen cord has run cool. In fact I probably killed my TR prematurely by using 100 foot 12 gauge cord since its motor windings overheated. I found a Hitachi jack hammer manual online which is probably applicable to all these cheap hammers of similar design.

for $150 you can't beat it. My guys took out 200 sq ft of 4" thick sidewalk,then used it for 3 more hours digging with clay spade (must have accessory https://www.amazon.com/gp/product/B002VMZBFY/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 )in dirt and still was doing just fine heat and durability.The oil reservoir is leaky & awkward to use, but over all, can't be beat for power vs price.

This demo hammer has far exceeded my expectations. I have a larger electric breaker hammer and a larger 2 stroke gas breaker. This breaks just as good as both of my larger hammers. It stays pretty cool and weighs about 40 lbs. It does not come with enough oil in the tool so make sure you fill the reservoir with a little over half of the provided oil bottle of straight 40 weight oil. I am very pleased with this tool and I am in the demo business. we'll see how long it lasts!

This tool is listed as weighing 11.8 pounds but it really weighs 38 pounds. The packing box stated 22 pounds and it was 54 pounds. Somebody need to get a new scales. The black storage box was broken.
