I was using my hammer drill to make holes in brick. It was going very slow and hard. That’s why I bought this rotary hammer drill and it made the work go much faster and easier.

works great
I was struggling to take out part of a concrete step drilling holes and using splitting wedges. Lots of prying with the wrecking bar and pounding on it with the sledge hammer. Progress was really slow so I bought one of these including the demolition chisel and a 4-cutter bit. Wow! This thing went through the concrete like it was butter and I drilled 1/2 holes in about 45 seconds. So much faster than my rotary drill! Wish I had gotten a tool like this years ago for drilling concrete and ...
Handles clay bricks perfectly
I used this to install a television mount into red clay bricks. The drill along with the appropriate masonry drill bit handled the job with no problems whatsoever.

Great Product, Disappointing Quality

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 cus...

Enjoyed Drilling Into Concrete!!!
I was installing a handrail on our front porch. I needed to drill into the concrete to secure the four posts. The house was built in 1991. I had a black and decker hammer drill, probably from 1991 as well, which I used on the first day of the installation. I had bought brand-new masonry bits to use. It took forever and alot of effort to drill eight holes. I was exhausted after it was done. My muscles ached! I felt like I was going to bend the bit from the amount of pressure I was using on the dr...
Worth the money
had to drill 5in 3/8 anchor holes for a 6x6 post, went the cheap route with a regular hammer drill and it was a nightmare! only got 3 inchs with one hole. bits got chewed up quick. bought this rotary hammer drill and got the job done in minutes, SDS is definitely the way to go.
