Recommendations sought - angle grinder

[Norman_E]

For slab cutting I bought one of these, mainly because it had soft start and came supplied with a diamond disc. http://www.ukhs.tv/Tools/Power-Tools/Wolf-2300w-9-Angle-Grinder The original diamond blade supplied with it has cut through a large number of concrete slabs used to relay a big patio, and the extra disk that I bought elsewhere remains unused. I tried diamond discs in a 115mm angle grinder and it struggled to do anything more than cut shallow grooves in the hard concrete, whilst rapidly wearing the discs.

Get a visor. About £7. Those bits that fly up and hit your face don't half hurt.

They do a damn good job of melting small holes in trousers, fleeces etc too.

Thanks All. seems there's lots of potential for dressing up when using these properly
Lots of good ideas and things to watch for. the slabs are only 5cm thick - I'm replacing inserts set into steps to overcome dishing due to 200yrs of foot traffic and ther are only three to cut down, so not worth buying a big grinder for - i may look to borrow or hire one for the job.
If i do decide to buy one, I'll treat it separately from a polisher and get something specifically for that job or resign myself to long days of mind-numbing effort. Up to now I've always been able to sort things on the boats without recourse to a grinder but i'll be liveaboard from end of next year and thinking that having one along would be useful.
cheers
