VEVOR Demolition Jack Hammer, MAX 1400W Electric Jackhammer Heavy Duty, 2900 BPM Concrete Breaker, 2pcs Chisels Bits Chipping with Case, Gloves

This thing is a Hoss. I busted up a bunch of concrete, and for the price, I figured if it lasted the job, it would be well worth the money. The equipment is holding up great and this was a worthwhile investment.The weight is kind of heavy but it's a big jackhammer, it has good grip, the design seems functional. It is noisy but it's a jackhammer... I'm sure it's quieter than commercial grade equipment. The speed and acceleration works great in busting up relatively large areas of thick concrete.Worth the money. Would recommend

I was on the fence about getting this; I already have a name brand SDS max drill so I thought this wouldn't be much better... I was pleasantly surprised to find out I was wrong; this thing is a beast, it tore through a 4-6" thick concrete path with ease, I took my time and still did around 32 sq ft in about 3 hours.I'm glad I read the reviews before hand so I knew it needed the oil adding because in the manual that bit isn't explained until the end. Mine did come with a tube of oil so I just needed to add it. That said, the manual is pretty decent and easy to follow. As others have said, the case isn't really going to stand up to being dragged around but it's nice for storage. In my area, this worked out cheaper than renting one for a few days, so I was skeptical but I'm really impressed with it.

Works as expected. Is a bit heavy, but that is a must for this tool. Only reason for the 4 instead of 5 is that the handle cracked on the first used and the pointed bit tip broke off on the first use. All other aspects are great. It has already paid for itself. I would have rented the same tool for $85 per day. I have used it a full 3, 8 hour days.

I don’t write many reviews, but this is an awesome tool at a great price. Don't think twice if you’re trying to break up concrete.

I can't believe how well this did . Needed to cutout about 8 feet for a basement bathroom. It busted out the concrete floor with no problem. It paid for itself on the first day . It's gets hot if you run it continuously so don't push it too hard .

Amazing machine. Used it to open the basement floor with no issues. Latter on I used it to cut concrete to install a window. Very versatile as long as you can carry it. Love it.

Please note my problem is not with the tool it actually works very well and well worth the price so 5 stars for Vevor. My issue was item was on sale in my cart only for the price to go up over $20. Whatever I needed this for a job I had coming up. Said it ships prime with delivery by Monday which left a week for it to arrive. Didn’t need it until Tuesday. Well after they raised the price now they say it won’t arrive until Thursday 7pm and it’s coming UPS. I purposely picked this because it was to be shipped prime which is usually 2 days. It’s no use to me on Friday because we can’t jack hammer concrete at 7pm in a residential neighborhood and it’s gotta be done by Thursday. So not only did they raise the price they lied about when and how it would arrive. Now I’m out over $180 for a tool I now have to rent anyway or put the job off another week. So this cost me more than double what it should have. When it did arrive I will say the tool worked quite well breaking up 6 inch 12x8 slab of concrete for over an hour no problem. Used the pointed bit and leaned into a little and about 30-60 seconds it broke right through concrete. If I had to find something to complain about with tool the bit was a little tough going in but I should’ve put some grease or oil on it to slide in better. So again the demo hammer is awesome but I’ll be canceling my prime membership after this I’m done.

This review is for the 1400 watt model. I had to bust up a section of concrete that was 12" thick, 18" high and 32" wide, then dig through the caleche clay that was underneath. For those not familiar with caleche, it's like digging in asphalt. You hit it with a shovel, and it just chips out a small chunk. The chisel and spike bits that this tool comes with made relatively quick work of the concrete.The goggles that came with the tool are not of very good quality, but would be better than nothing. I used safety glasses that I had for other projects, along with a good set of earmuffs to protect what is left of my hearing. (A lesson that I learned too late in life) The tool is not exactly light weight, but it needs to be heavy to work and hold up. I'm 70 years old, and could handle it fine. It is well worth the price paid, as it would have cost 3-4 times that much to rent a tool for as long as the project took, and I still have the tool for any other projects in the future. The trigger lock button was very helpful in that it allowed me to use it in positions that would have made holding the trigger in the “ON” position uncomfortable and awkward.For the caleche clay, I purchased a 2” wide chisel to fit the demolition hammer. It worked great.If purchasing chisels for this unit you must be sure that you are getting what they refer to as the 5/8" hex shank style. On that style chisel, the round end section measures 13mm (.5") in diameter, and the hex portion measures 17mm (.7"). (See photos) The SDS, BOSCH, and larger hex chisel bits will not fit this model. I could not find a clay spade that would fit this demolition hammer, so I used the 2" chisel to break up the caleche clay, then a regular shovel to remove the broken-up material. Using a spade, you would probably still want to use a regular shovel to remove the material anyhow as the hammer would be too heavy for shoveling material.Also noted, this model does not use oil in a reservoir with a sight glass. There is a reservoir that contains grease to lubricate the mechanism, and I also coated the shank with grease to prevent wear. Clean the old grease off when changing chisels and remove the excess from the chisel retainer section. (Similar to air tool quick connection couplers.) The unit comes with a container of grease.
