    • Excellent Tool
Style: w/ (2) 12V Batteries
Great tool that I didn't know existed. Always used pneumatic die-grinders. Battery does not last like a pneumatic one, but gets the job done, plenty of power, especially with the different setting levels. Nice set, size is good and price is decent for Bosch tools.

    • Great tool for its intended use
Style: w/ (2) 12V Batteries
I purchased this angled grinder because I needed to get into tight spaces on metal sculptures that were difficult to do with my pneumatic die grinders. This tool works as advertised, it should be noted that I do not force the grinding, but let the tool use speed to do the job. The batteries last longer than I anticipated and the tool is ergonomically designed to be comfortable during long use. This is a great buy for my intended use and a welcomed addition to my toolbox. ... show more

    • Good for light duty if using for metal work
Style: Industrial
All in all, it's satisfactory. I had higher expectations but I needed to be more realistic. Don't expect this to compete with an pneumatic angle die grinder. I tried carbide cutters and it will perform but obviously don't expect to hog. If you're deburring, then it's perfect. Roloc pads are about the best you can expect with this, again good for deburr. Guaranteed this would perform if it was 18V but would take away the compactness of the 12V. Do get the biggest 12V battery if you want better performance and longevity. ... show more

    • It’s smooth and compact. More so than the Milwaukee’s
Style: Industrial
I have both the Bosch and Milwaukee gen 1 & 2. I’ve had the first Bosch and Milwaukee gen 1 for about 3 years. I did have to swap out the original gen 1 Milwaukee for a replacement because it died shortly after buying it. They are all great performance wise, but the Bosch feels more refined and it’s smoother when running in hand. The Milwaukee gen 2 is the most powerful but that’s not really necessary or most important with a compact angle grinder. It’s more about speed control, smoothness with low vibration and quick attachment changes. I like the quick lock on the Bosch best. The Milwaukee Gen 1 is atrocious with having no spindle lock and having to use two different wrenches to loosen the collet, the Milwaukee gen 2 has a lock making it easier and less cumbersome than the gen 1. Also Milwaukee gen 1 trigger and safety lock is terrible to use, it’s just like the ones you hated on the older air die grinders. The gen 2 got some better but the safety still gets hung sometimes. The Bosch just seems to be easier to use over all, it’s smoother, a little lighter, triggers easy to use and it’s a little more compact. ... show more
