Dong Cheng 1-1/8 Inch SDS-Plus Rotary Hammer Drill with Safety Clutch, 9.2 Amp Heavy Duty Corded Demolition Hammer for Concrete, 3.6 Joules, Including 3 Drill Bits, Flat Chisels and Point Chisels

Strong and powerful in a solid case with bits included. A fraction of the price of Milwaukee. Perfect if you're not going to use it every day.

So long story short: we came in and had to knock out a failed mortar bed for a shower that a previous vendor had incorrectly installed. Like other reviews, I can attest that this thing is a seriously heavy-duty tool. It was the other reviews, in fact, that gave me confidence to give it a try. It's packaged extremely well, feels solid, and was totally affordable. We own a few rotary hammer type of tools, but this thing has outdone them all.

Dont be fooled by the name. This is a really good hammer. Strong tough and reliable. This thing blew bosh out of the water. and heck of alot easier on the wallet.

This isn't some Milwaukee or Dewalt tool, but it did do the job it advertised. I received the tool, put it together, set it to hammer drill mode, and off to the races it went. It did excellent with the bit I chose, drilled 4 different holes through 50 year old concrete in 2 minutes tops.However, I then went back through those same holes with a slightly larger bit (working my way up to 5/8's), and as I was drilling out the second hole, the bit caught on the concrete and refused to spin, making quite an awful noise in the process. I stopped, pulled the drill out of the hole, and started again. This time it got a little further, but still it caught somewhere in the concrete. It still hammered while caught, but refused to spin the bit (basically switching to hammer only mode). I was a little frustrated, so I pulled the tool back up, switched to hammer only mode, and went back down, try to clear off the sides of the hole from whatever rock or pebble in the concrete that might be catching the bit (or maybe even rebar, I wasn't sure, but didn't see any sparks). After that I switched back to the drill mode, went at it, and it finally quit catching. It caught again in the last hole, so I used the same trick and it worked just fine.Overall, it did the job better than my Milwuakee drill with a hammer function did, and by a long shot. For the price I paid, it made quick work of the concrete and would've done a lot more if I needed it to. A little on the heavier side, but it's completely worth it for the occasional use.

I bought this for removing some tile which it did easily. I bought the 3-inch wide chisel also which I love. The real test is that I lent it to a contractor working on my house to remove over 300 square feet of concrete tiles. This hammer chisel with the 3-inch chisel powered thru all the tiles mostly popping them up intact. The tiles were in place 35 years and it was easy to get them up. This is a heavy hammer drill, but not expectingly so. Bottom line is that it's a great tool at a great price.

Awesome power for the price. Came w bits too! Used to set a hot bolts for auto lift. Maybe 15 seconds per hole at 6 inches.

I used this during a crawl-space earthquake retrofit (Bay Area CA), drilling 68 6" deep holes into the concrete foundation. They took about 30 seconds each. I don't understand how a heavy-duty drill like this can cost $80. It's a great bargain!

This rotary hammer is well made and was great for tearing up tile and the cement board underneath. It has the rotary function for drilling into cement and also has a setting where it doesn’t spin and just hammers. This is important to know because some rotary hammers only spin. You should always check this when looking for one. The price was great and I was pleasantly surprised by the quality of the hammer. The name “Dong Chang” ( not a well known name brand )had me thinking that it might be something that wouldn’t last long but not only does it have the color of a Bosch tool. It also is equal in its quality.I would definitely recommend this product and the Dong Chang brand.
