Got a nice piece of granite (1 3/4") to use as my bas for sandpaper
sharpening system, but I need to square it up.
How do I cut granite? Is it time to find a counter top guy who has a diamond
blade or what?
Thanks for the suggestions....
You can make small cuts in granite with an electric grinder and a suitable
disk. Difficult to be accurate, the finish will be rough and I would never
attempt to smooth or polish even a small piece of edge with ordinary
You need a diamond wet saw to cut your granite. Most tile installers and
many stores have one for cutting tiles, including granite tiles. A local
installer or store may be willing to cut your granite for a fee.
You might want to take a look at
http://www.gardengatemagazine.com/extras/76cuttingstone.php which has a
couple of nice videos that show how to cut stone with a hammer and chisel
and with a diamond saw.
Wet saws aren't all that expensive and are useful things to have
around. I bought one a few years back for tile and have used it quite
a bit. HarborFreight has a fairly nice one for what I paid for mine
A case of beer might get an installer to cut it for you. He might
even share. ;-)
I'd be inclined to visit a local headstone shop, but if the angle
grinder idea has appeal, then something like the fifth and sixth photos

might work as a holder to run along a straight edge.
A friend of mine cuts granite using a hand-held circular saw with a special
blade, runs water over the cut to keep things cool, and has a GFI on the
power source for the saw. I'd want pneumatics for this, but he makes nice
cuts, and is still among us.
i cut lots of granite slab using an angle grinder with a 4" dry diamond
blade, if it's too large to fit on the table of my tile saw. don't breath
the dust, btw. if you want a polished edge, you need a water-feed
grinder/polisher. i use this one:
depending upon the size, just find a tile guy. home depot will cut it for
you for not very much/cut.
I'm a bit late to the party. Use a diamond masonry blade in your
circular saw. A low-cost one will do fine.
Clamp on a fence, and take 1/4" passes. Dry. And reasonably quickly.
Outside with goggles and dust mask, stay up-wind, because it gets some
I do this all the time.
