I bought this for helping me with relieving paver stones and steps. I pulled up the stones and steps. Then added paver sand and tamped with this tool. If I had to do a larger area I probably would rent a temper. I have not used the other ends that come with it.
I have used it 2 times so far, for breaking up a piece of concrete slab, it worked well, as far as jackhammers go it is decent. I want to buy the other attachments Vevor sells for tamping dirt etc, but I will likely use this 1 time a year.
The shack hammer did everything I needed and then some absolutely a beast. Ran this thing for 45 minutes straight It did warm up a little bit but powered through it like it was nothing.
I really like the way it works is it put together easy and holds up real nice and it's you know great feeling with you know just jackhammer so it's really really good
You would pay about the same to rent one from Home Depot or United Rentals for 1 day! I used it to take out a double set of concrete block stairs and a landing 5 feet tall. I don't have any bad things to say about it. Good quality, great price and who cares if it breaks tomorrow but I don't think it will. The Bosch I rented before couldn't do the job and it was the same build. Don't hesitate just buy!
The tool does a good job. Breaking concrete is real work though.
I am a 60 year old DIY guy in good shape. I was able to use this to break up a very thick concrete pad (6\" in some places) in a few hours which included hammer breaks to pry bits apart and move them out of the way. Breaking up a freestanding chunk not bound by other concrete is very quick if you make some big fragments. I started with the chisel bit but ended up doing most of the work with the pointed one. After you do it awhile you will get the hang of how to fracture stuff and how to prevent bit binding. If you break off the sides so the concrete has a place to go the cracking is much easier. Buy some ISO 46 oil when you get this. YouTube has videos where people add the oil by removing the whole cover plate. No need to do that. Just remove the sight glass fill plug and add until slightly down from the top. Also add some grease to the bit where it inserts into the tool. Fiddle with the lock pin until you know how it works and the bit stays in. It is not as loud as I thought it would be but I recommend hearing protection. I also used a full face mask. There will be some dust also that you may need protection from in low wind conditions. It's a good tool. I got the 2200W one. I had previously purchased $300 worth of concrete saw and blade and this is much faster than that method.
