Berserker 1700W 30-Pound Demolition Jack Hammer with 1-3/16" Hex, 14-Amp Corded Electric Heavy Duty Demo Chipping Hammer Concrete/Pavement Breaker with Carrying Case Flat Chisel Bull Point Chisel

What the other 5-star reviews said. This demo hammer gets the job done. It took me some time to figure out the right technique but once I did it works great. It's heavy and I'm getting quite a workout just moving it around but it does the rest of the work.I bought it to break up some concrete that I thought was 4 inches thick. Turns out it's 6 inches but the Berserker is undeterred. This job has already taken me 3 days so compared to renting a demo hammer it has already paid for itself.

I've used this tool for a few different project so far, and it is a beast. Seems well built and just keeps working and working on whatever you're trying to break up. I'm so glad I didn't get the vertical-only jack-hammer, because being able to use this thing at an angle can be extremely useful. It worked on a 6-inch concrete driveway and a boulder that we dug up in the yard. It does take some control and strength to keep the machine pointed in the right angle as it pounds away. You certainly need to be physically in good shape and have upper body strength to wield this tool effectively.

Bought this in the hopes of breaking up a rock close to the house limiting access to drive around. Worked surprisingly well. Learning how to best use it but making great progress. Only down side was case arrived broken at left side clasp, so won’t stay completely closed. Otherwise great tool and value.

4 stars only because the case was a little cheesy but it did the work at a reasonable price. Homeowner use but might not be the best for professional daily use...(but you pro's out there already knew that)

Great tool! Works as expected

Good jackhammer for the price. I had lots of concrete to break up.

Doing my bathroom renovation and had to break the cement floor to get to the shower drain. Took less than 5min what took me 2 hours with heavy hammer the day before. Well worth it even if you are doing one job. So much power.

I had a large tree stump in my yard the I was trying to remove but the roots had grown between the layers of the large rocks under the stump preventing me from removing it. I used this tool to break up the rocks and undermine the stump enough to allow me to finish the job. The rocks were no match for this tool. It is fairly light and maneuverable but heavy enough that you don’t need to force it through what you are trying to break up. I cannot speak to the longevity of the tool and whether or not it will last, but it seems well built. For the amount of times I will use it as a homeowner, I feel like it will probably stand up to that use without issues.
