Customer Reviews for VEVOR Demolition Jack Hammer Concrete Breaker 3500W Electric Hammer 2 Chisel Bits

Choose the right bit for the right job and it works. I run this off my portable generator and as long as I am using the correct bit, it works very well. I have had no problems with it in rock, limestone, granite, iron rock, hard pan clay, compacted dirt, gravel. I check the oil level in it before, during, and after use, I make sure it is clean and I make sure the bits are in good condition.

This hammer worked great. Did a great job for me. Price was great. I'm buying another tool from them today. I couldn't be more pleased.

A large, thick concrete slab was lifted up by water-laden soil beneath, partially blocking my garage door. A sledge hammer did very little to reduce it. Rather than hiring a contractor or renting a jack hammer, at greater cost, I took a chance on the Vevor 3500 watt model. I appreciate the instructions, safety accessories and nice storage case. The hammer is heavy but easily controllable with the adjustable grip and it smashed through the concrete in an hour, so the door now opens easily. What an impressive piece of equipment! It definitely rates 5 stars.

Bought the 3,600 watt version to break up a concrete walkway while digging out a driveway by hand in Hull, MA …two kids in college will drive you to extremes… but I’m 57 and needed to get in shape anyway… anyway, the undisturbed earth was too tough to break up with manual shovels (my 24 and 21 year old sons came to help at the start of the project, and we made very little progress). I had purchased the demo hammer which came with the point, chisel, spade and flat bits, so I started using the spade bit to cut out chunks of earth. So I ended up using the spade bit to cut out and loosen up chunks of soil. This made the work easy, and little by little I was able to excavate the driveway. The tool worked wonderfully. The point, chisel and flat bits all broke through the concrete admirably- not sure which one worked best, but the flat bit was definitely helpful in cutting out uniform square chunks. And the spade but was fantastic at cutting through the loamy topsoil as well as the rocky clay soil in the ground about 18” beneath it. (I dug down as much as 3 feet or so in this project… As for the tool itself: It’s somewhat hefty, so be prepared to lug it! I’m 6’1” and in decent enough shape to still do physical labor, so it wasn’t an issue for me. But if you are elderly or if slight build, you will want to note that it is a heavy tool… Set up for the machine was easy, although I couldn’t find a ton of literature about the type of oil to put in the machine. (I’m not sure where to find #46 oil, or whatever they recommended, …but I did find reviews and info that mentioned 15W 40 oil… but even that was only available in a gallon size… so I used 10W40, seems fine. In case you don’t figure it out right away, the little oil fill level sight window on the side of the tool is where you add oil. The 3/4” or so nut holds the sight glass down and I think there’s a little gasket there too… anyway, over time, the oil got a cloudy milky appearance. I thought perhaps some water had got in, so I changed the oil…but I have since concluded that it was an air emulsion and haven’t really worried about it. As some other reviewers have mentioned, the handle in the middle of the tool is comprised of a 4” bolt spanning two side metal arms that attach to a collar that encircles the middle of the tool… this bolt holds the handle together with a nut at one end. And the nut DOES work itself loose quickly and requires attention frequently. Tightening it down with a wrench is definitely recommended… but it will work loose again over time. Overall, this Vevor electric demolition jackhammer saved the entire project!! And DON’T LET THE LOW COST FOOL YOU! This tool for the money is A BEAST (I paid $169) You can trust Vevor and they are extremely responsive too (had also bought the 6” tamper bit for tue demo hammer, but was going to return as it just wouldn’t have worked for a project this size. …end

The jack hammer was awesome. It performed much better than I expected. The weight and performance exceeded the previous jack hammer that I rented. The rent for more than two days was more than the new Vevor jack hammer. Now I have a wepon for those tough jobs.

muy buen servicio envió muy rápido aunque no lo e probado espero que funcione bien para futuras comprars

It is just as described. Well built and heavy. It works very well. Needed to dig out cement footings and rock hard clay. It chewed through like it was sand.

Worked great and made the nasty job much easier

I do commercial plumbing, so you know this thing is getting abused. I swear every time I use it is just like the very first time. Literally, I have used this well over 100 times and it runs like day one every time. I do obsess over cleaning up properly, not many are but I promise you it is worth every damn penny.

Very Pleased with the price and overall performance.It got the job done . it did save me somr hard work breaking up ths hard ass concrete that i had to remove .thanks for that
