Circ saw blade to cut quartz countertop??

[shoottmx]

Need to cut down a 48" long piece of 1" thick quartz. Just looked at a bunch of 7 1/4" diamond blades at the borg but none specified quartz. There were Makita blades there in the $35-45 range that were for granite. That kind of price is good, as long as it's the right blade for the job. I don't imagine it will ever be used again. Does anyone have a recomendation?

Thanks,  Gary

Any diamond blade will cut it but it should be wet to get a clean cut and for the blade to survive. Those 7" diamond blades are really for small tile saws.

Yes, they will cut it.  But, I wouldn't even try that dry, wet only.   I've use a clamped guide and a normal saw with a solid rim diamond blade with a trickle of water from a hose to do that.  Start with the saw on the edge away from you and draw it backwards so that it cuts downward.   Works best for me using a LH saw blade.  Just a little water.  If your not comfortable with electricity and water, be sure it is plugged into a GFCI circuit.  

Or, best practice, replace your saw cord with one from a pressure washer with the GFCI built in.

You fellas that are crying the sky will fall if quartz is cut dry are mis-informed.  There are plenty of blades designed to cut dry, and even a wet blade will cut 4ft. of 1" quartz.  Not for very long, but on a one off job; it'll get it done.  Same goes for polishing pads.   Whether you just need to resize the piece and the cut edge is hidden , or it needs to be "money" cause it will show has bearing on blade choice.

We use one of these all the time to cut porcelain, quartz, granite , and marble tiles and slabs.  Attached to a vacuum and it is quite handy and convenient for a quick re-size or cutout in the field.

Depending on what you are doing an angle grinder is another choice.   I have a Hilti blade I use in my skilsaw, an Alpha Saw for cleaner cuts and curved blade for cutting curves that works in the Alpha or angle grinder.  Water is best for all, besides cooling it keeps the dust down you don't want to breath much of it.  I am not going to say I have never done it dry as I have but the dust is a pain unless you have a fan blowing it away from you. 


Edit to add don't use a cheap angle grinder if you use one. I had 2 of the lower cost Makitas catch fire. The weakest part was the switch and that's where it burned. Also turned the lowest cost Hilti into trash within minutes of taking it out of the box, that one does not have much of a warranty the HD manager covered it because I was back in the store within an hour of the purchase

I am not sure about the load a 7" blade would put on a skilsaw  I use this one I bought a few when HD was closing them out

There is a water kit for a skilsaw
This is an example it seems expensive to me but you get the idea I would look elsewhere

If you have some scrap to practice on do that.  The first time cutting stone can surprise you.  I am clearing out my stash of counters and slabs soon.  I am pretty sure any new work will get done by writing a check, then again I am thrifty


Forgot to mention use blue tape to mark your lines I think it also helps with chipping. The white out pen will mark stone I prefer using tape

NOPE, sky won't fall, but it'll sure get cloudy!   That's the main reason for water, dust suppression.  As a bonus, a solid rib blade used with water will leave fewer score marks on the cut end.   If it will be polished and exposed that could be important.

You will feel that dust if you breath it in.  It is not good
