Bosch GWS 9-115 900W 4½" Angle Grinder 240V is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from Brilliant Bosch angle grinder I purchased this to cut Bradstone natural sandstone paving slabs - it was brilliant. It was powerful enough to cut like a knife through butter (with the aid of a Marcist diamond disc) without being so big as to not cope with smaller more intricate cuts. It was easy to use and adjust the guard in order allow different cutting positions. No problems with any kick backs. My only regret was that I hadn't bought this angle grinder far sooner.

Rated 5 out of 5 by from Brilliant little grinder Without a doubt the best 4.5 inch grinder I have ever used. Soft start makes it easy to control, the extra power means the motor never labours, and the tool-free guard adjustment is a brilliantly time-saving design. I bought this when the brushes wore out on a Bosch Pro grinder I have used heavily for 15 years or so (and which is back in use now that spares have arrived). I am delighted to find this new grinder shares lots of common design features with my trusty old machine, so I am looking forward to a long life from it. Everyone who has used it has commented on how nice it is to work with. It's far from the cheapest grinder, but I'm happy with the price / performance trade-off.
