Cutting concrete with circular saw

[ian]

I've cut small sections of concrete using an angle grinder. Replace the 'metal' disk for one marked 'stone' and it will get through it like a hot knife in butter. Plenty of dust. Do it in stages. The disks aren't expensive.

Plenty of dust is one way to give yourself a case of silicosis.

Far, far better to use the dust bag on the Makita diamond saw to collect as much of the dust as possible.

Even better is a fully ducted saw connected to a proper dust collector.
