Rated 5.0 out of 5.0 by trogo Rotary Hammer Has Good Ergonomics, Anti-Vibration and Power
If you are in the market for a mid-sized rotary hammer, look no further than the Bosch SDS-Plus 1 1/8 Inch Rotary Hammer, Model RH328VC. The first thing I noticed is how well balanced the tool feels and easy to use. At 7.7 lbs and 14.5 inches wide, along with a very effective anti-vibration system, it’s designed for all day use. I am very impressed with the tools ergonomics, features and performance.
The Bosch RH328VC Rotary Hammer has a powerful 8 amp variable speed motor, delivering 0-900 rpm, 0-4,000 bpm, and 2.6 ft-lbs of impact energy. It has a capacity of 1 1/8” hammer drill bit and 3” concrete hole saw. The RH328VC includes an all metal gear case and mechanical clutch to protect the motor in case the bit binds. It includes three modes of operation: rotation only, hammering, and drilling and hammering. It also has a mode for accurately adjusting a chisel style bit when hammering. A side handle is also included which has an integral depth adjustment rod. It took only a few seconds to drill 3/8” holes through 4 inches of concrete.
Overall, I am very pleased with the Bosch 1 1/8” Rotary Hammer. It’s small enough to be very comfortable performing small jobs, yet large enough to perform the vast majority of tasks most users will ever encounter.

Rated 5.0 out of 5.0 by AntMan Thor Can Have His Hammer – I Have This Hammer Drill
This is one of the best tools I have ever gotten. And I am not exaggerating one bit. I
recently completely a project where I put down a sand based patio in my backyard
which is fenced in. In order to put down the track for the pavers to sit in, I had to get rid
of concrete that my fence posts were planted in for stability. I took out this hammer drill,
bought a SDS chisel bit, and went to work. First off, the hammer drill comes in its own
carrying case which is really nice and convenient. Setup and usability was a breeze. I
read through the instructions but basically just inserted the SDS bit in directly, hooked it
up to power, and started going through each setting to get a feel for it. It has multiple
settings of operation, from drilling alone, hammering alone, and drilling and hammering
together. It also has rotation feature to get the chisel in the correct axis for you. And it
has a forward and reverse spinning gear to switch over to. This hammer drill went
through the concrete posts like it was nothing. It literally just pummeled the concrete into
pieces. It was almost effortless. It was so effective that I drilled out extra concrete just
for fun. Nothing slowed the hammer drill down – it was fantastic. The tool isn’t overly
heavy and feels like it is built to last. It’s not too noisy and is plenty powerful. So
powerful in fact that I actually got the bit stuck when I went too deep into one of the
concrete blocks. This was not the tool’s fault – it was my own user error since I chiseled
in too deep and actually got it lodged in the wood base of my fence. The special vibration handle dampens a lot of the harsh vibration so you can continue to use the tool for awhile. It does require a
SDS bit, but if you feel the need you can buy a 3 jaw chuck for it so it can be a little
more versatile. Again, what a great tool. The true testament to this tool is that my father,
who isn’t usually a fan of “fancy” new technological tools, absolutely loved it. He
continued to praise it and said it was the most impressive tool we bought for the entire
patio project (and we bought many, many good tools). Well done, Bosch.

Rated 5.0 out of 5.0 by ToddB THIS DRILL ROCKS! AWESOME!
I had never used a real hammer drill before. Not sure why. I wanted to split an overhanging end of a granite step, so I ordered some 1/2" feathers and wedges and borrowed a neighbor's Bosch Bulldog drill. OMG! That was so easy I couldn't believe it. I just had to get one for myself.
I didn't do too much research, but I did discover that the "1-1/8" size is the maximum drill bit size that the drill is rated for. I don't know what material they rate that in (concrete?), but it's all relative, so the larger the more powerful the drill is. This drill seemed like a good price point for me and I liked the vertical format over the horizontal of the Bulldog.
I've now drilled and split a number of granite blocks, some 10" thick using this drill and a 1/2" carbide bit (Bosch HCFC2081 1/2-Inch by 4-Inch by 6-Inch SDS-plus X5L Drill Bit). I've also drilled and split a number of foundation stones in front of my barn so that I could cozy a large granite landing up to the sill. . Those were difficult to split, but each hole only took about 30 seconds to drill. I bought a longer carbide drill for future rock work.
Let me assure you that this drill and a 1/2" carbide bit will drill a four inch hole in a stone or a block of granite in 30 seconds. I drill 18 holes down the middle of a six foot block in a matter of minutes. What's more, there's no need to push on the drill. I just hold it upright and let the weight of the drill and the hammer action do all the work! This means you can work for hours drilling with no fatigue.
I also used the chisel action to remove a 100 square foot area of pavement with an asphalt/stone underlayment. For that i used a chisel (Bosch HS1470 SDS Plus Viper Long Life Chisel). I think this was pushing it for the drill. It's not really a jackhammer, of course. I got the job done, but it took quite a while and was a tiring job. The chisel bit sacrificed its life for the job, as well. My neighbor says it should have been easier with a pick, but it's too late for me to know. I don't think you should expect a drill this size to handle hard code chiseling demo work.
The SDS PLUS chuck is "ok". It's a bit tricky to get the bit seated, but it's not enough of a problem to influence my recommendation. I didn't realize there's an SDS MAX chuck. Not sure if it's just in more expensive drills, but it might be worth a look for you. I think bit price and availability should play a big role in your decision of chuck, though.

Rated 5.0 out of 5.0 by Historian Work Smart With The 1-1/8 Inch SDS-Plus Drop Down Rotary Hammer Drill.
As the old saying goes, you can work hard, or work smart! I've been re-tiling my house, and was killing myself with the old fashioned hand scraper to remove old tile that were really stuck in place. I got this Bosch 1-1/8 Inch SDS-Plus Drop Down Rotary Hammer Drill Model RH328VC and my life just got a lot easier! Paired up with the Bosch Tile Chisel, this beast tears up tile like nothing I have ever used before! Bosch makes a whole bunch of other SDS-Plus accessories that I now look forward to trying out, including the Bosch 1618571014 SDS-plus Shank 3 Jaw Chuck so I can use my regular drill bits in this drill. I really love the extra large trigger on this hammer drill, and the simple to use controls. The depth gauge was a nice addition to it as well. Even the carrying case is well-built and has enough room to store extra bits. All in all, I love this beautiful beast! Thanks Bosch, and Home Depot!

Rated 5.0 out of 5.0 by markkapusta Great tool with versatility
Bought this hammer drill to drill and mount my ledger board for my deck. Delivered great power and speed in drilling threw my brick veneer which is 4" thick brick. Drills fast and clean holes with the bits I purchased. Also bought a demo pick and chisel which both worked great for the job they were used for. If you are looking for a lite duty demo/rotary hammer drill this is it. Don't expect to demo out a sidewalk without pushing this tool!

Powerful and yet feels comfortable to the grip, this rotary hammer works like a charm. The usual Bosch quality I can trust. I expect many years of good service from this Bosch rotary hammer.

Rated 3.0 out of 5.0 by oldguy123 versatile with the ability to switch
I used the tool mainly to remove a stone wall around my fireplace. I used the hammer drill and drove in wedges to break up the concrete as well as just the hammer. It work well in the lighter wall but in the thicker base it took more time.
