SDS-MAX Demolition Hammer is rated 4.3 out of 5 by 10.

I chose the Milwaukee tool because they have a reputation for good, professional tools. They didn't disappoint with this demolition hammer. For now I had only a small project, making a hole into the concrete slab under the house for a sump pump. For this the Milwaukee Demolition Hammer was total overkill, but hey, it made this small project even quicker. I have more demolition coming up in spring and so this was a test run. The demolition hammer works really well. With the right attachment tools it goes through concrete like a warm knife through butter. This tool is very powerful and it didn't even get warm with my 3" slab. Looking forward to using it on the bigger projects.

While not inexpensive, you get what you pay for and this Milwaukee product is worth it. I have a lot of tools in the Milwaukee line and this one is as good as the rest. This tool is essential if you are demo-ing old tile with the metal lathe & mud behind it. This is a demo hammer without rotation but there is a setting that allows the chisel to freely rotate so you can line it up with grout lines. This is a big, heavy duty demo hammer but it can do smaller jobs like cleaning mortar from bricks (but build yourself a stop as a helper). It has two hammer settings. Standard noise level. Side note: the case is plenty big enough to store without perfectly winding up the cord and can store plenty of chisel bits in it too.

This demolition hammer is one strong beast, no getting around it...This thing is big, extremely well constructed, packs a tremendous amount of power, and will plow through most anything you throw at it. I had a small project to bust up part of my outside concrete pad to incorporate a small fire pit. This project was on my back burner for some time, due to initially trying to bust it up with a sledge hammer and chisel. This proved to be one of those going nowhere jobs that lasted forever. I then had the chance to use this demolition hammer. Holy smokes....After using this demolition hammer, my small concrete pad was completely busted up within two hours....Two Hours!!! Previously, it took me forever to go nowhere using a back breaking sledge hammer and chisel. This things absolutely rocks. Hands down, this deserves a close look if you're on the fence about getting one. Extremely pleased to highly recommend this beast of a tool.

I am not associated with Milwaukee but I own quite a few Milwaukee power tools and I love them. Milwaukee makes great tools. This demolition hammer is no exception. Powerful to get the job done quickly. Offers good grip and good balance on weight and power. I am retiring my old one.

Rated 5 out of 5 by from Powerful Demolition Hammer We purchased this demolition hammer to demo floor tiles in our house. This is actually overkill as it's very powerful. However, most Home Depots don't carry the next model down. This equipment works really well and makes removal of floor tiles quick and easy. Just a note: the handle can be swiveled around to make it like straight with the user. For some reason, the Pro Desk at Home Depot and even the customer service people both at the store and over the phone didn't realize that. We figured it out ourselves.

Rated 5 out of 5 by from Fantastic tool Used this tool to demo about 750 sq ft of tiles throughout my house. Using a Bosch tile chisel bit made easy work for removing floor and wall tiles. I have done this job previously using hammers and pry bars and this cut the work load by 75%. Took longer to clean-up then to demo.
