It's Bosch quality
Style: Industrial
Not a whole lot to say about this grinder other than it is Bosch quality and performs as expected. It will go through a battery (4 AH) fairly quickly but I prefer to uses with my smaller batteries rather than add the weight of a large battery. I like the x-lock system, it is so much easier than messing with a threaded system. ... show more

Good quality Bosch tool
Style: Industrial
I was a little skeptical about getting a battery powered angle grinder that was only 18v. After using it for 3 months I'm satisfied that it will handle everything I need it for. Might not work for a full-time welder or iron worker but it will work for most DYI'ers or moderate use.

What an improvement in our working efficiency!
Style: Industrial
I was skeptical of the X-loc system. The replacement discs are so much more expensive. However, its increased productivity immensely. Changing discs is so quick. It eliminates the need for having 2 grinders close at hand all the time. One cutoff and one grind. Just switch back & forth in seconds! And of course, Bosch makes a great tool for the job as well. Powerful, quiet and reliable. It doesn't seem to eat up batteries too quickly. Which brings up its only downfall, however unavoidable. The balance of the tool with anything but the smallest battery available makes the tool kinda unwieldy. The weight is all hanging off the back end. It still beats dragging a cord behind it though. It works on 18 volt batteries only. Though, the old 12 volt chargers will charge the 18v batteries without a problem. ... show more

Excellent Lifesaver
Style: Industrial
Absolutely fantastic for a quick job out in no where. The quick changing X-lock system makes any job relatively easy with just one grinder, instead of typically having 2 or maybe 3 hanging on the side of the table - cut, grind and brush. A 4Ah battery isn't exactly sufficient for maybe 30-min use. So a minimum of 8Ah is best. 12Ah is better but makes the overall unit heavier and the balance is a bit shift to the back. Not a problem for me working on metal but just be aware when doing fine cutting on ceramic tiles. ... show more

Great little grinder
Style: Industrial
I got this specifically for my wire wheels for welding. It works great for that and X lock saves me a huge amount of time. Takes 2-3 seconds to swap a wheel instead of minute or more. Keep in mind this as an 8 amp equivalent grinder, Bosch Also makes a 10 and 14 equivalent so this is their least powerful cordless option. Still plenty of power for most tasks, wire wheels, cut off wheels etc. Feels just as powerful as an 8 amp corder unit. It will run a flap disk but will cut out if pushed hard, that is really more suited for a 10+ amp grinder though. Great Bosch build quality as well, definitely a step above the Red and Yellow brands. You can't go wrong with this unit, especially for the price. ... show more
