Is there anything I should know about circular saws and masonry blades
before I attempt a finish cut on a 2" limestone cap on my front deck?
Will this damage the saw or the limestone? I've seen masons do this
with big, honkin' internal combustion saws and large blades so I don't
know if my Milwaukee will have the juice for it. Or if the dust may
Do you have a gas-powered lawn edger? I put a masonry blade on one and used
it to cut concrete. It worked great and got the dust etc further away from
me. The adjustable depth control was a plus (normally used to adjust along
the sidewalk, curb etc.). It's been a while but I'm pretty sure I was able
to keep the surface wet while I was cutting.
If you have more than a couple cuts to make, rent a gas powered concrete saw
with a diamond blade. It's a little cumbersome, and kicks up an ungodly
amount of dust - but it's definitely the correct tool for the job.
In my limited experience the cutting is slow going and the dust is
nasty. I would not use a good saw and I would - did wear full face and dust
protection. The saw I used was an old Sears I bought as is about 35 years
ago for $3.50. Nothing will kill that thing.
You can get a dry Diamond blade for your saw, There was a water feed made
for a circular saw at one time. If they still make one that would increase
the blade life and cud down the dust. When they did our granite the used a
dry diamond blade (6"to 8") in a grinder, I have used a 4" grinder ( some
times called a peanut grinder) with a diamond blade to cut tile and stucco.
If you use a regular abrasive blade I can't imagine how long it would take
or the dust but I've never cut Flagstone.
Limestone is quite soft, a resin masonry blade and your saw will work
just fine. Just go slow and easy, don't force. Forget a diamond
blade...they make dust too and it would be silly to buy one for one cut.
Possible but I use my circular saw with a masonry blade occasionally to
cut concrete caps - about the same as your limestone would be as far as
hardness and abrasiveness - and haven't damaged my saw. Clean it well
after, blow out dust from the inside too.

I just installed a small patio/landing for our deck steps and had to cut
some pavers in half. I used an abrasive blade on my saw, and had my wife
standing next to me with the garden hose nozzle set on "trickle" wetting
down the cut as I did it. This kept the dust down to a minimum and seemed
to help keep the blade running smoothly.
Of course you don't want to get the electrical part of the saw wet -- just
the blade area.
