Yes. I bought a couple diamond blades for my ancient B&D 7 1/4" saw
years ago. They eat through block or old concrete. They dissolve
if you hit re-rod.
mine is something like this-

The dust is horrific. I've tried taping my shopvac nozzle where it
does the most good. Works OK. . .sort of. . .
But one time I got brave, plugged in to a GFCI outlet, and dribbled
water from a hose right where the blade meets the cement. That's
a winner. I doubt the water is as bad for the bearings as the dust
was-- but I'd use a 'sacrificial' saw for the job. Get one at a
garage sale for $10.
Yes, a masonry blade will but a concrete block. It will also generate a
butt ton of highly abrasive dust, which will work wonders with your circular
Wear a good particle mask and get a cheap circular saw. Do it outside,
where the wind will carry the dust somewhere away from mammals.
I disagree & I've tried both. The angle grinder gives less control,
won't cut as deep, and is just as dusty. The up side is- you can
usually get an angle grinder for $12 at harbor freight- a saw will set
you back $30.
But speaking of HF--- anybody used the multitool to cut block? That
should gain you control-- and have way less dust.
[no job is worth doing if it doesn't involve buying a new tool]
A brick mason's hammer? I could cut a cinder block with one.
Even try a chisel and hammer.
Michelangelo? Why are you hammering that stone?
There's an Angel in there and I'm trying to get him out.
That's a skill I've never been able to acquire. I have never done
much masonry- but can get by in a pinch. I can break bricks and
blocks into smaller pieces-- but never have been able to get them to
break where I want them to. [though I've learned that block can be
mortared back together fairly easily]
I've had a little better luck with an air-chisel. But I still cut
them. . . dust be damned.
Some granite installers were putting in kitchen fancy stuff. Most all
was granite tops cut at the shop.
Watched the HMFIC, cut granite trim with a 4" angle grinder. A diamond
blade and by using a wet tile spong near the blade. The sponge trick
kept the dust down. It was a nice job from that crew. Some cuts have
to be done on the job.
I see mexicans doing this all the time for pavers, my neighbor had a
walk way put in, the dust made was a cloud 50ft x25x25, it was real
nasty and bad for the tool and people breathing it. Renting some sort
of wet saw is the only way to go.
