I need to cut some small driveway blocks. Though I know nothing about them
I've got into my head that I need a small angle grinder with appropriate
discs .. is this correct ? I'm surprised to see corded DeWalt models for as
little? as £40.
I'm having to temper my internet shopaholism with the need to find out what
will do the job best for a reasonable price tag. I'm not going to have to
cut too many and they're only 5cm thick - will an angle grinder do the job ?
I may have to extend it's use to cutting some natural sandstone paving
slabs - I don't mind if it takes a while.
I've only started looking into this tonight so please forgive my naivety.
No, you need a big one - more reach with the larger disk.
Cheap 9" grinders are 40 quid and weight twice as much as a good £80
one. Diamond disks are cheap these days and eBay is a good source.
Or hire something.
A block splitter will do it, but is a bit specialised. An angle grinder
is more useful as a general purpose tool.
Decent angle grinders are actually quite cheap. You will need a 230mm
one for that thickness of block. Get a decent diamond disk to go with it
and it will cut quickly and the disk will last for ages (i.e. longer
than 100's of ordinary abrasive stone cutting disks). Don't forget
decent ear, eye, and respitary protection when using a grinder for this
- they make serious dust!

My small Lidl one would not be man enough for that job.
I would go to the local Tool Hire shop for a bigger one for paving slabs.

I'm sure there are some blocks that a splitter works perfectly with, but
my experience with them was disappointing. To make a good job, the cut
faces need to be flat, and the splitter left my (Marshall concrete)
blocks anything but flat. Their main advantages are speed and freedom
I had a lot to do, so I bought a chop saw (similar to
and a diamond disc - it made an excellent job, for straight and angled
cuts, even for long slices down to 3/4" or so. It's also useful, with
an abrasive disc, for cutting steel sections. I also bought a
secondhand Stihl saw, again with a diamond blade, because I had a number
of hefty edging blocks to cut.
A stihl saw would be OK for your blocks and your sandstone, and there
are plenty for sale in local free ads papers. They need a certain
amount of care and reasonably strong wrists and forearms to use safely.
A small angle grinder might cope, if you use a diamond disc and don't
mind cutting from both faces, but a 9" one would be better.
As an aside, are you sure about using 50mm blocks? I'm not convinced
they're thick enough. Not that they'll break, but the limited thickness
doesn't provide the "wedging together" effect of thicker blocks that
block paving relies on.

A slow but safe way is to use one of the larger wet tile cutters which
will cost about 50 quid in the sheds. You'll probably have to do it a side
at a time if you want a perfect edge, or just split it after making one
I'm terrified of angle grinders for this sort of thing...

I have recently extended my drive with block paving. I own a 115mm and a
230mm angle grinder, both with diamond blades.
However, I hired a block splitter to do the job, /much/ quicker, and doesn't
produce the dust storm from an angle grinder.
The angle grinder will probably do a (slightly) neater job, in a longer time
with more dust. For a few blocks I'd use the angle grinder, but non-diamond
blades don't last long, for more than a couple of dozen blocks to cut I'd go
for hiring a splitter.
