Rated 5.0 out of 5.0 by Awesome Tool I purchased this tool to remove an old fireplace in my house. It did the job easily. This is my first Rotary Hammer so I can't compare it to anything else, but it made pulling apart the fireplace an easier task. My only pet peeve with the tool is that my finger kept getting pinched by the trigger. I resolved this by wearing gloves, which I probably should have been in the first place. I plan to use the tool in the summer to remove a ceramic tiled floor. I only hope it works just as well on that as it did on the fireplace. January 16, 2012
Rated 5.0 out of 5.0 by Impressive Bought this rotary hammer for a basement finishing job and used it to chip out high spots in the cement around some lolly columns as well as drill about 150 holes for Tapcons. Couldn't believe how fast and smooth it drilled through the concrete floor. Just watch out how hard you push using small-sized SDS-plus bits - broke off the 5/32" bit after about 75 holes. That's when I got a chance to drill a few holes with my old 6 amp regular drill. Drilling holes went from about 5-8 seconds to taking a full minute and with a lot more force on my part. Needless to say, I went out and bought some new SDS-plus bits the next day. This was my first Bosch tool of any kind. A short 3-months later and I now own about 5 other Bosch tools. I'm a believer.

Rated 5.0 out of 5.0 by Great Product Used the Bosch to demo my guest bathroom, it handle the tile removal no problem. It also handle the demo of the floating walls all the way to the studs. Did pretty good job on floor, but had to borrow the bigger Bosch brother to remove the hot mop shower floor. Great with the wide blade for tile removal easy would recommend! March 14, 2013
Rated 5.0 out of 5.0 by excellent chipping gun I use it to demo stucco when i am doing repairs It does the job better than the air chisels but it will heat up and shorten its life. I keep 2 of them and let them cool down and they last way more than twice as long that way. My only gripe is in changing the brushes. You take off the handle and all the wire connections are so short that you have to put the handle almost back on again and reach through inside the handle with needle nose pliers to reconnect the wires. Bad design on that one. EVIL design I should say. Brushes last a long time though. I would like to try the SDS plus. It has heat dissipation built into it and anti vibration for only about $50 more.
