Have had this model for several years. As others say, with a good bit, this tool will bore a hole through concrete like a knife through butter. I also used a wide scraper bit to easily remove an old ceramic tile floor. It is an indispensable tool for heavy-duty work.

I'm a homeowner who bought this tool 1.5 years ago and have used for two different bathroom projects to break up tile - once when I first bought it and again this week for a second bathroom renovation. When it works, it's really great! Unfortunately in my case, today it started smoking and sparking in the motor compartment half way through our tile demo. Immediately stopped using it, looked up the warranty and sad to find out it's out of warranty (1 year warranty). Called Bosch and their customer support was very good (rare to find these days) - didn't wait long, the agent was very knowledgeable and supportive but the best they can offer is that I can send it back to Bosch for repair (max total repair cost = $142 including shipping) and will take 5-7 days without shipping to repair. Given a new tool costs in the $200 range and I'm in middle of project I now either need to pause the project for 2 weeks for a $142 repair or go buy another new Bosch/explore different brands. I understand the 1 year warranty so not complaining about that but for a tool of this brand reputation to break after two light-duty uses is disappointing. Wish there was a better warranty or Bosch offered better options for cases like this.

I bought this a month and I am happy that I did. Super useful

Great tool. Will be great to use on a couple more projects I have. Easy to use and not so heavy or loud as some I've seen. Drill and Hammer action works great...put in sump pump - great tool.
