What should I get to do this?
Screwfix are doing a Dewalt 9" grinder for £70 - would this be alright?
And also, which discs should I go for - this'll be basic builders
merchant supplied conrete slabs.

If they are solid concrete slabs it'll be hard going with an angle
What you REALLY REALLY need is one of these, and now is you excuse to
buy one <G> :

It need not be. Remember you don't have to cut all the way through - a
groove (possibly half-depth) will suffice with a full depth cut right
at the ends.
Plenty of good advice at http://www.pavingexpert.com/cut_in01.htm
I recently laid a patio with about 20-30 slabs requiring cutting and
my standard angle grinder (with cheap stone cutting discs) worked
Have to agree with Mathew - I cut 10 in half using the small angle
grinder, just putting a groove along each side, so that I could put an
edging round my veg patch.
The limitation on an angle grinder is the depth of cut.
Done mine with a Makita 9" grinder and budget diamond blade from
Screwfix (which is still going several jobs later). Very easy work but
just make sure you keep your body clear of the line of the grinder.
I'm sure the budget £15/£20 grinders work just as well.

Diamond. Dirt cheap these days - check eBay.
Cheap angle grinders usually work as well as good ones, but with
obvious lifetime limits. However the big difference is that they weigh
around twice what a good (£80ish) one weighs. For cutting slabs flat
on the floor this is almost an advantage, even though it's normally a

Lump hammer, bolster chisel and tin of elbow grease.
Stone cutting or a diamond blade in an angle grinder will cut a slot and
make *lots* of dust. Once you have a slot about 3/8" deep along the entire
face and down the edges place the slab, slot upper most, over over an edge
and snap it.

Not if the slab is thoroughly wet first..
The traditional wetting agent for diamond is olive oil. Not that I am
Is the diamond really diamond?
