Cutting paving slabs

[Hagbard]

I need to cut some paving slabs and was going to buy an angle grinder. However, none of the ones I've looked at specify a maximum cutting depth. Does anyone know what size of angle grinder I need to cut 40mm paving slabs?

9 inch cutter will be fine

Agreed, but if you can only get a 115mm one, then cut part way thru then tap with a bolster - the slab will break well enough. It just depends on the quality of the cut edge that you are after. Don't forget, if you cut concrete slabs, you'll simply expose the concrete inner, so arrange for that face to be hidden.

Thanks for the advice. The edges won't be exposed and gaps between slabs will be grouted so I'll probably go for a 115 as they seem to be widely available and considerably cheaper than 230 mm ones.

scoring a slab is fine for straight cuts, if you wish to cut a 90 degree section out of the slab, then a 9" angle grinder is a MUST.

Nah, you just gotta be creative!

You don't need to spend a lot on a grinder, in my opinion. I have a 9" one (fnar) that cost a few quid from Q&B, its lasted years without probs. I have been through two Bosch 115s in the same time.

Spend more on the cutting disk, though. A good diamond blade will last and will slice through slabs with ease, without the need for pressure.
