  • Great Grinder
I bought this for my husband after his beloved Hitachi corded grinder finally pooped out on him. I was nervous about going cordless but after repairing our old grinders power cord several times I decided to try it out. I purchased the bigger 6.4(?) battery for it because my husband is a mechanic and uses his grinder a lot, so increased run time is needed. luckily I already had a charger as I also own the impact by Bosch. It was a hit at Christmas, now my dad wants one too lol. ... show more

  • Sufficient for my needs
It's powerful enough for what I need it for. I'm just an occasional user. This would be considered the base model of bosch18 v line of grinders. but because i don't use it everyday it suits me just fine. I've read reviews that critize the positioning of the guard, and how it's impossible to adjust. Not true at all. You can, and i have, you just have to read the directions, and know how to use tools. It's that simple. I've adjusted mine to any position that I want with no problems. Just have to know how the tool works. As for as using the tool. It's not the most powerful. I'm running the 4 amp core 18v battery, And it's serviceable. If you're an everyday user of a grinder than you'll probably benefit from one of boschs professional grade ones. It's great for an occasional user. ... show more

  • Bosch
Big Bosch fan and this grinder doesn't disappoint. Plenty of speed and power. Handle is a little awkward coming from a corded grinder but nothing can't handle with ease.

  • Great value for the price point.
I did not have the problem that others had mounting the wheel guard, there is a certain way it goes on and it takes some patience to get it completely installed. As far as it’s performance, it’s seems alright so far but have not put it thru extended use. Over all I think it’s a good value especially if it on sale, for me that was $99 before tax. ... show more

  • Love it
Very powerful, uses batteries from my other Bosch cordless tools. It's a tad bulky and did not come with a battery, but not that much of a concern to subtract any stars. I love not being tethered to a cord! Got it for $99 and I think that's a great deal. And it's Bosch, so I expect excellent longevity out of it like all my other power tools. ... show more

  • I love Bosch 18 volt battery tools
I love Bosch 18 volt battery tools. This one is a great addition to my collection. It has way more power than I expected. I use it in my garage, even when I have a 110 volt angle grinder available. It is nice to not have to mess with a cord getting in the way. Outside my garage, it is way better than trying to use a generator to run a 110 volt version. ... show more
