grinder discs - concrete

[Jupiter01]

I have a Makita 115mm grinder and wanted to check if there were any recommendations on the discs I should use to cut fairly chunky 600x600 slabs? I have a Screwfix and Toolstation down the road and planning to do this afternoon.
Would welcome any tips. Thanks!

Erbauer diamond discs are decent. Don't say I told you so but most 115mm grinders will take a 125mm disc and give a slightly deeper cut.
