I Call it Mjölnir ( Hammer or ThoR)
This is an Engineered MasterPiece!! I have just drilled 48 holes in brick and mortar ( started with brick and had a brick crack so I drilled slower into the mortar and had no other issues or cracks)! I felt minimal vibration in my wrist/hand due to the designed movement of the handle. I have only used about 1/3 or 1/2 throttle on this thing and it just pulverizes the mortar even drilling about 1.5 inch from the brick edge without cracking once I eased off the throttle!! If you are in need of a professional level contractor grade hammer drill look no further!!

    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.

    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.

    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.

            Works and works
            [This review was collected as part of a promotion.] I've used this quite a bit over the past year to core holes and break up old post footings. Works like a champ. Doesn't bog down.
