Diamond saw blades

[lue]

Hello I have a question about diamond saw blades. Most of these are used on a saw that has a pan full of water. Is there different types of diamond saw blades that yield different results (course and fine). I have a diamond saw blade and am not to sure what type it is if there is different types. Also, I don't have a saw with a pan of water on it all I have is a tablesaw. Do you think I could get by with feeding the 12 by 12 marble piece into the blade while a spray water on the blade from the top with a spray bottle. I would make sure the saw is on a gfci switch and I'll probably lubricate all components of the tablesaw with wd-40 before this so nothing is damaged in the process. Thanks for the help

Hi Lue,
Dangerous. Trying to protect yourself with a GFI breaker spraying water over an electric motor is not a good idea. And the dust will be very substantial. Think "dust storm". Your tablesaw motor won't like the dust either.

You need to rent a wet saw to cut the marble. Or if the cut edges are going to be hidden under base or shoe molding, you could get away with using a 4" angle grinder and diamond blade. It isn't nearly as precise, but it's cheap.

Its not safe to do this. an over heated tile blade could fly apart.
You may be able to find a dry blade that will be acceptable for your table
saw. i know that roofing guys buy dry blades for skill saws although i havent
bought a 10" dry blade myself. I do use dry blades for my 4" grinder all the
time. hang tight im sure more help will come along.

This is a *really*bad*idea* for both the saw and the tile.

Yes, there are all sorts of diamond blades. I have some 4" blades that are no thicker than a razor blade and cut a tiny kerf. There are also blades that can be used wet or dry. Even if you use a dry cut blade, mounting it on your table saw is still a bad idea for the saw and the tile because of what the dust will do to the motor and mechanism and bad for the marble because of heat buildup. It's also a bad idea if you have neighbors. They won't be happy with you when they see the gynormous cloud of dust heading their way to engulf their homes and cars.

Thanks for all the replies. On my last project I did this. On this one I thought about it abit and was concerned about it so I figured I better ask someone. On my last project I hooked up a shop vac to the dust chute so there shouldn't be a problem there. For the spray bottles I used one of those continueing sprayers so It lubricated the blade and the marble piece enough. I suppose the main problem is water being near an electrical motor like that. I figured that if there was a problem the gfci switch would catch it and prevent any damage to the saw or myself. I understand, it is being risky. Unfortunately, I live in a small town and there is no place to rent something like this. Well, for know, alittle unsurity of what to do right know is here.

Lue,
Tell us more and we can help clear things up. For starters, what is the project and are the cut edges going to be exposed, or hidden behind molding?

I recommend buying a cheap wet saw. I bought a $95 wet saw a few years ago at Lowes (home depot has similar). Rental companies wanted 40-45 per day, although much heavier duty. I've done about 6-7 tile jobs and on my third blade, but saw still working fine (and I don't have to hurry to get the saw back before 5pm). Good luck.

and believe it or not the cheap wet saw will cut marble ,tile ,etc. only you go a lot slower ,due to weak motor. if i had it to do over i would have invested 250 to 300 dollars bought a better quality or spent 600 to 800 bought an even better quality ,then re-sold it on ebay when i was done with it. i made the mistake of buying the 88 dollar wonder .i have now done 8 tile jobs with it one being 440' of 18" porcelin on diagonal ,you have to mark tile and free hand it but the dang thing hasnt died yet.on its 3rd blade.

Ok Ill tell ya something true. I set up an old radial arm saw for cutting tile used a water pump running on it. I got the sh&t shocked out of me that was one the top stupid things I have done. do not do it.
