I LOVE my rotary hammer drill … it has never failed me and punches holes in concrete as if it was butter. I drilled 50 1/2″ holes 4 inches deep into a concrete slab in 1 hour, such a time saver for my business. Solid and rugged, just what a professional needs for the job site.

I used this to install 60 Simpson Universal Foundation Retrofit Plates. They need 1/2″ x 5″ Titen HD bolts installed into the concrete foundation. This Bosch rotary hammer made short work of the holes. I could drill the holes to 6″ or deeper in less than 30 seconds. Quite nice when you are crawling around under your house. It’s the perfect size for lugging around under your house while still being powerful enough to get the job done. I’ll use it in the future for light jack hammer work and whenever I need to drill a hole in concrete. You won’t be sorry you bought this tool.

Was able to get the job done in half of the the time, compared to a drill motor and a bit. Very well built and handled well.

Great performance for only 7-pounds. One reviewer’s complaint about the lack of a trigger lock is not well thought out. When the bit catches, you need to quickly let go or the torque will rip your arm off. I also bought the optional 3-jaw chuck so I could use straight shank bits from a my regular drill. This will be my go-to drill for any job more demanding than an electric screw driver.

Feel and build quality is excellent! Haven’t busted it out in any big jobs yet but can’t wait to! One thing to note, this is only one letter off (in the mode number) from the same thing without the interchangeable chuck. Accidentally got the wrong one first.

An Great Rotor Hammer to be used for most all demo jobs as well with extra needs for drilling and chipping away concrete. Bosch the brand name one can be comfortable with using it hour by hour.

i bought this hammer drill to drill holes in a giant rock in my cellar and then use wedges to split the rock. with the Bosch concrete drill bits this thing goes into the rock like drilling through wood. i could not be happier with this tool. also got an accessory flat blade bit and now when i dig in hard clay i use the hammer drill and a hand pick is a thing of the past. this tool is great and i really mean that. its effortless to use.

I have had my hammer for over 4 years now and I do professional demolition work. It keeps me going when others are in the repair shop. I am a very hard person to please when it comes to tools and this one is a great one. I have never had it let me down and have done some big jobs with it.

This tool takes the work out of the job when removing old tile flooring as well with some concrete chipping around the drain areas of tubs.

Used this tool about 5 times, once to drill into concrete, and the other 4 times to remove tiles and thinset. Great tool, I bought it because of its size, I didn’t want a bigger demolition hammer because of 2 reasons: so that I don’t damage the plywood subfloor, and to not injure my back after hours of opperating a heavier tool. I think that I made the right choice, although I’m sure that I would’ve got the job done much faster with a bigger demo hammer.

I have been using this tool for over a month. All day, five days a week.I am very happy I bought it. So is my boss because it saves a lot of time.I mainly use it to chip tiles off bathroom walls of drywall, plaster, concrete, and cinder block. Usually glued on but sometimes thinset, which is a pain ( for thinset I use a 3/4″ chisel ). Drywall can be very tough to save if there is not enough support behind it but I found that if I pair it with the Bosch 1.5″ Tile Chisel I have a better chance. You just have to not use any of your own strength to push under the tile and just let the tool do the work. One kick on the side, and those tiles just pop like popcorn :-)I have found that after running the tool for a while ( I’ll guess an hour straight ), when I press up against something to chip, it will just vibrate for a second or two before removing a part of the tile. It looses it’s “kick” which is slowing me down, and not doing the amazing job that it usually does. Once I come back from a break, it’s working fine again.When this dies, I’m buying another one.
