Bosch DGSH181K 18 Volt Cordless Die Grinder - Review
Imagine if a Dremel mainlined Human Growth Hormone and anabolic steroids for weeks on end. The result of such an ecstatic binge of doping would be a massive, bulked-up handle with a spinning head capable of whirling an abrasive bit into thick metal. It would be a durable tool that could withstand the constant abuse of a jobsite and remain unfazed at being casually thrown into the back of a pick-up truck. This newly engorged tool would look exactly like Bosch's new cordless die grinder.
Bosch sent us one to check out a few months ago and we've had it on site for most of that time. We have to say that a die grinder isn't exactly a day to day tool (at least for general wood frame construction), but if you come across particular situations where it can be used, it's invaluable because no other tool is quite like it; rotary tools are too delicate and grinders are too large and wild. The Bosch splits the difference offering both strength and finesse.
We discovered the tool's usefulness when we had to go through the entire first floor and shave a little strip of protruding metal off of all the old electrical boxes that were set in the the baseboards. A full sized grinder would have been nearly impossible to use due to the delicate nature of the work (and the newly refinished floors). We needed something that was strong, but that could also be controlled. The die grinder was a perfect fit. If we hadn't had the tool kicking around, we'd probably still be there working away with hand files.
There were a number of other times when the tool came in handy; grinding down a cut off screw, fine tuning a tile scribe, and tinkering with a strike plate to name just a few off the tops of our heads.
So it's a handy tool. We really wish that it had a speed control, but it doesn't, so when it's on, it's on at full blast. But at least there is a really nice soft start to it. The handle is also really comfortable and we never felt any fatigue while using it.
It'll be a few months before we're going to be able to get our welding set-up going, so when that happens we'll really test the waters with this tool, but after what we've seen using it in the general construction world, it should hold up nicely and the fact that it's cordless will be a big plus when cleaning up welds and inside corners.
The 18 volt tool has a 1/4" chuck that spins at 22,000 RPM. The items (with battery) weighs less than 4 lbs. It comes with one of the fat batteries, two wrenches, and a nice, large duffel bag.
Amazon is selling this tool for $300, so it's not one for the weekend warrior. But if it's something you're going to use, well then....
Bare tool only ($220) at Amazon
