how to cut sandstone and slate

I want to know if I can use those mason saw blades they sell at home depot for around $6-$12 to cut sandstone and slate.They look like a big cut-off wheel (impegnated)for a circular saw and are labeled for masonery.They are not a metal/diamond blade.Can I use these?If so,wet or dry?

You can, but if you have more than a few peices to cut, you are better off with one 30-50 dollar diamond blade instead of 6 or 10 of the "cheap" ones.

How thick is the stone you're trying to cut? A circular saw will only go about 2 inches, and you DO NOT want to use it for wet cutting. You could get a heck of a jolt. The fiber blades will wear down quickly, so in short order you won't even be able to cut 2 inches deep. The diamond blade is the way to go. I've bought some relatively cheap ones at Menards before, probably $40 or less for one that fits a circular saw.

On 2-3" thick material I would only score the material 3/4"-1" and break it. Are you using it on flatwork or in a wall?

You use the diamond blade to score it.

I've cut tons (literally) of stone with nothing but a cheapo Craftsman circular saw and a carborendum (sp) blade. I only score it about 1/8th inch then lay it on a bed of sand. I built a lil box to hold the sand.. Then I rapped (hit) it sharply with a brick chisel till it snapped. For a stubborn piece, just go from one end to the other with the chisel till it parts. I might lose one piece out of 50... Bill in Va.
