We use Bosch for all of our grinding needs. We are an Historic Masonry repair company and use Bosch Grinders and Vacuum cleaners to extract the dust we create. They are rugged, reliable and longer lasting than any other brand.

A little bit expensive for something made in China, but works so far.

Bosch siempre es calidad, llevo usando esta esmeriladora un tiempo, le doy un uso ocasional y para trabajos pequeños. Para mi en lo particular me ha servido muy bien, tiene mucha potencia un buen tamaño y es muy ligera.

Decided to pick up an extra grinder for masonry use. I originally got the GWS8-45 and wasn't happy with it, as it seemed to run a tad too hot amongst a few other things. I was worried at first this one would have too fat a grip, but it's about perfect. While it is a bit bigger than the GWS8-45 in the grip area, it seems to be easier to hold due to the shape and textures. I also like how this one is normal length and feels more balanced than the GWS8-45. It's also 8.5 amp which is a plus.The function of it is about typical of an angle grinder, I have no complaints so far. I've used it outside in high temperatures with moderate use and heat wasn't an issue, but the gear box does get hot; which seems typical of these Bosch grinders due to how they are setup inside. The spindle spins true and no abnormal vibrations with or without a new diamond blade. I find unlike the switch on the GWS8-45 (which seems to be easier to accidently set off even though it appears to be a thicker in size switch), only when gripping up very high, this grinder doesn't have that issue.The only con I can come up with is I wish the bottom cover/guard mount that seals the spindle, gears, etc.. inside, fit tighter around the screws or just in general sealed better. I notice that grease can slightly seep out over time or as it gets hotter. Not sure what the reasoning is behind that but I doubt it's too big of an issue.Overall I am pleased so far with the grinder and it performs as expected.

Me sorprendió lo ligera que es está herramienta, tengo 2 de motor más pequeño y están más pesadas, lo único que no me gustó es el gatillo me parece sumamente frágil
