This hammer is awesome. While not a commercial grade tool, it is perfect for a homeowner. It easily broke through ten inches of concrete that I needed to remove The hammer is heavy but I considered other demolition hammers listed on Amazon and the reviewers often said the hammer's housings were made out of plastic. This hammer is mostly metal and appears to be well made. Before using it, I suggest that you look at YouTube videos on electric demolition hammers. They all work basically the same. YouTube will show you how to attach the bull point, how to add oil, what type of oil to use, routine maintenance and how to properly and safely use the hammer. While this hammer cost a little more than other hammers listed on Amazon, it is well made and powerful. I would recommend it. One last thing. I contacted the seller three times with product questions. In each instance, the seller responded quickly. The buying experience was excellent.
