Rated 5.0 out of 5.0 by 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. July 26, 2013
Rated 5.0 out of 5.0 by Fast and Powerfull I have always used the rotary setting on a regular drill or rented a Bosch hammer drill. I have a lot of earthquake tiedowns and mudsill bolts to install soon so I figured I should buy my own hammerdrill. I have only drilled a dozen or so holes with it and it has saved a lot of time and effort and allows for more precise drilling. Should have bought it sooner. December 11, 2014
Rated 5.0 out of 5.0 by great german made rotary drill I once thought a hammer drill was a hammer drill, till I tried to drill through my 11inch thick foundation. You definately need a rotary drill for this application. 35minutes with a noral hammer drill turned into under a minute with this one. Like the hilti i used to use at work, but not the size a jackhammer. Solid product that has exceeded my expectations, for a great price for what you get. September 4, 2014
Rated 5.0 out of 5.0 by never go back to a regular hammer drill I am amazed at how fast you can drill into concrete vs a regular run of the mill hammer drill July 25, 2014
Rated 5.0 out of 5.0 by Great hammer drill Just finished using this tool for the second time. First time I used it to mount 8" anchors in basement walls for a stair landing platform. Used it two days ago the second time to bust through a block foundation wall for a crawlspace access. Good tool for the money. May 19, 2014
