Block splitter for indian sandstone?

[DanSW]

Hi, I have about 25 x slabs of 22mm riven calibrated indian sandstone (imported) that I will need to cut. I only need a single cut to each. I have limited angle grinder experience, although do posess one. If I can get hold of a probst block splitter, the one with the teeth for uneven surfaces, is it preferable/quicker for a newbie like me?

Thanks

No you need to cut them. Get a piece of ply you can put on slab, put one foot on it so it don't move and use it as a jig to cut a straight line.

Thanks Sean, I was trying to convince myself that the splitter would be a lot less hassle but angle grinder it is...

The clay-paver (toothed) splitter would work on *some* of the flags, but would quite probably ruin the other half, so not cost effective.

Whenever a spllitter is used to cut/trim flagstones, it's always a hydraulically-poweered model. The force required to apply even pressure capable of splitting stone over such a length is more than can be applied manually, even with the telescoping lever handle and a right fat abstrad on the end of it!

Thanks, I was worried about the potential wastage when using such a device.

I have a 4 inch angle grinder and some diamond discs but I can borrow a 9 inch angle grinder and a commensurate diamond disc. Is there much of a difference for what I need as I believe I am only cutting halfway through and then tapping with a hammer to finish the split? Or if I am using a 9 incher is it that I would cut all the way though with the extra diameter?

Thanks

I can only encourage you to hire, or, borrow a petrol cut off saw. With electric you can't use a water dust suppresant, unless you wanna be zapped? The dust from slabs/flags is harmful to your health so dry cutting is a no no.
