Tried the grinder on the last job and find it slows me down and I'm just not keen on it.
Wet cutters next to me and with the grinder it's outside to cut or invest in a decent extraction system and I don't know if they are any good tbh.
Would consider getting a curved blade for shower quadrants mind I've mastered the art of doing them and can do it on the wet cutter in no time.
Think the OP is new to the trade, maybe best with a wet cutter as I think using a grinder it may be easier to run of line or chip tiles if doing it for the first time and you will probably be stressed enough lol you could buy a cheap grinder and decent blade as you will need it at some stage and a few old tiles/cuts and practise to see what suits you best
