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.

This thing is an absolute beast! I had a problem with trigger sticking on the unit but Amazon sent another one promptly - I could not say enough good things about this jack hammer! It’s amazing! It’s heavy but it went berserk on my concrete pilings. It broke anything I threw at it…

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)

Materials very good quality. Have used it several times to help with break up hard ground soil. I would recommend the product.

I live in Puerto Rico, so there’s very few things that they will ship here. A lot of companies do not have sales tax agreements with Puerto Rico. Nor do they want to pay the extra amount of shipping cost because of the weight to ship here. I gotta tell you. After opening the box. Seeing the quality. Seeing how heavy duty. And I used it to break up some concrete on my back patio. I gotta tell you dollar for dollar pound per pound, and they should’ve charged twice as much. It’s just that nice. So if you’re looking for a jackhammer at a great price, don’t look any further. Now I’m sure this isn’t something that if you’re a commercial company you could probably use every day at 365 days a year. Only because I haven’t used it that much. But this will be worth every single dime that you paid for it. I’ve used it six times now and wow, it does not let me down.

Had to tare up a side walk at our house. I was going to rent a jack hammer but the price for one day rental was more than the cost of this product. Liked the reviews. This unit is terrific. I broke up the side walk which was 6” thick in no time. Recommend this product 100%.

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.
