Just been laying a sandstone patio, having finished laying the full flags I am now starting on all the cuts. I tried one today thinking the angle grinder would chew through it in no time. To my surprise the grinder with a stone cutting disk was struggling, in the end I used it to score the cut line and ended up splitting it with a chisel which was OK for the one done but some of the other cuts need to be neater. The hardness of the stone has surprised me some of the shards chiseled off are so sharp you could perform surgery with them. Would investing in a diamond saw prove any better? I see Aldi has one on offer this week.
