Dead after several uses [Posted on 2006-10-27]
Looking for a replacement for my Bosch drill that just died, I ran across this 1199VSRK unit here and must note that the Bosch predecessor to this drill (the 1194VSR) just experienced the same "death by use" problem. Drilled maybe 10 holes with it, when all of a sudden it lost variable speed control and would only run full tilt. I changed to a smaller bit, as it was running too fast for the larger one and when I next pulled the trigger, the drill ran for about 0.2 seconds and is now dead.
Maybe Bosch needs to go back to the electrical design lab and create a better variable speed control module!
Dependable workhorse [Posted on 2007-08-17]
I've found this tool to be a dependable workhorse in the class of work it was designed for. I've used it on jobs that involved hundreds of concrete drill holes, typically 1/4". I've had it in use for 90 days and it's a keeper.
I bought it because Bosch makes excellent rotary and demo hammers. It's the only Bosch tool I own. My equipment includes Milwaukee, Dewalt, Makita, etc.
12/29/07 My experience with the 1199 continues to be 100% positive. We put this type of tool to heavy duty use, drilling concrete and block. The tool sometimes undergoes multiple hours of run time in a single day. The 8.5 amp motor stays cool under work load and has never exhibited any indication of significant strain. Letting the tool do the work is critical.
Sizing the tool to the job and using it correctly are essential when working in a business environment. My reason for selecting this hammer drill was the power weight balance. It's a two hand drill that comes in at 6 lbs. and offers high and low torque capability. Any frequent work above ½" in concrete essentially requires a rotary hammer which is typically a heavier tool.
Previous reviews noted issues with "wobbling" chuck(s) and electrical failures. Electrical problems typically become evident quickly and I'm confident Bosch's unconditional warranty holds merit. The chuck issue can quickly be addressed as the drill comes out of the box, brand new. If it runs true with a bit attached at max speed, no load, then the chuck is fine. The hammer action of this drill is serious business and should not be construed as a chuck fault.
I'm not particularly brand loyal across the board. I believe most contractor grade tool manufacturers have particular products that prove themselves superior on the job. I've since added another Bosch tool to my equipment, based primarily on it's reputation and my experience with this tool.
Strong and Smooth [Posted on 2007-09-04]
I bought this upgrade after I burned my Ryobi up. The job that killed the Ryobi consisted of twelve 9/16" holes into 1/2" thick steel and twelve 1/2" holes into concrete at a depth of 2 3/4", however, I was seeing blue sparks even before this job. After very slow progress on the first 9 steel holes and first two concrete holes the Ryobi quit. It had had seen some medium and light duty before that. It really struggled cutting through ceiling and floor joists with self propelled auger bits.
I brought in the Bosch to finish the job and it was strong and smooth. What a time saver too! It was surprisingly powerful on the high speed setting. It cut the steel and concrete both like butter one either the high speed or high torque settings. I took it around back after the job and tried some self propelled auger bits that the Ryobi had struggled with. The Bosch chomped right through the 3+ inches width of a pressure treated 2X4 without a problem on both high and low speed settings with 1" and 3/4" auger bits. There is no wobble in the chuck. It's a fine machine and it compares well to Milwaukees I have used in the past. It has also seen the worst I can give it.
Some finer details about the drill:
- It will take some getting used to pulling the key from the detachable holder and putting it back. I'm used to just grabbing the cord where the key is and going to work.
- Read the case and make sure you have it upright before opening it.
- The case is nice. Although it seems compact it has room for a box of bits and plenty of loose ones.
- Extra long cord is nice too.
- Depth gauge is reliable and sturdy (better than others I have seen.)
Update 1/08: I've used the drill for a few more jobs including some electrical work and some concrete with Tapcons. She is still running strong and smooth, and it's really a pleasure to use. I forgot to mention that it comes with an anti-kickback feature. Someone was helping with the Tapcons, and I saw them twist the bit pretty badly. The chuck stopped cold without even so much as a jerk. That's a nice safety feature to have on a beast like this.
Appreciate the slip clutch [Posted on 2008-05-21]
I just wanted to echo one of the earlier positive reviews and say that the integrated slip clutch is a great feature. It is not uncommon for bits to catch in masonry and when this happens you have a few possible results: a broken bit (stuck in the hole?), a bit that is spinning in the chuck, or a drill that spins into you. This slip clutch in this drill goes a long way to preventing all of that. I'm now a big fan of this feature and, regardless of brand, wouldn't buy a hammer drill without it.
Quick delivery & perfect for my initial purpose [Posted on 2008-05-25]
I bought this drill to install a gate in a sidewalk. It drove (8) 3/8" wedge anchors 2" into my sidewalk with no trouble in well under an hour. It was "reconditioned" so I was a little concerned but it perfomed like a marvel for the price. I am not a pro but I expect this drill would handle this type of job every day for some time.
