Limestone Cutting Disc

[efunc]

Hi all, I just bought a used Makita 230mm angle grinder and need a disc for cutting a few limestone paving slabs. They're 23mm thick. I notice there are general diamond discs, but also a 'stone cutting' disc which is cheap. Which type would be advisable?

At that price i suspect it'll not last as long as a diamond disc, annoyingly the diameter reduces as part of the wearing process so eventually you can't cut to depth. Should be fine for 'a few pavers'

Thanks. I suppose at this price it might be fine to try out, but like you say, a diamond one might cute quicker and cleaner, who knows.

Anyone have any recommendations on decent discs in the medium to economy range?

bought one last week. about as cheap as i could find atm.
screwfix used to do an erbauer. about £12 iirc. couldn’t find it , don’t think they do it any more.

Norton are OK IMHO. Stone cutting discs would be fine if it's a couple of slabs and that's it. They do take a bit longer to cut through and are a bit dustier. It's a long time since I used one as most people use a diamond blade now.

Is this the one, at about £15?

The stone cutting discs look cheap, but I might as well buy a diamond one I suppose. First time I've used an angle grinder so might as well use a blade that will make my life easier than have to wrestle with it. Actually, this Norton looks bang on the money. Not sure if it's as good as the erbauer, or better:

Aldi, or get a "Blue Spot" disc off Amazon around £12 or so and those are as good and last as long as any.

Stone carbonundrum discs are crap in comparison to diamond discs

Not used a non-diamond disc for cutting since I first bought an angle grinder about 20yrs ago, they seem totally pointless for cutting

Just went up on eBay and picked up a new Bosch Professional Plus Diamond Cutting Disc for just £12 around the corner from my house. Result. Googling the part number (2608600358) brings up some eye watering prices!
