How do you cut small square holes in small stone slabs?

Answer 1

I do it using a sandblaster, you can find (resist film) on-line. you cut a square hole of your choosing in the resist film apply glue to the stone, stick the resist on, burnish it down and then sandblast. (the longer you hold the blasting nozzle on the square the deeper the hole gets until you go all the way thru) NOTE: monument companies have large sand-blasters, some autobody shops have sandblasters also. Good-Luck

Answer 2

You can use a rotary tool with a diamond cutting wheel to cut small square holes in small stone slabs. Create an outline of the square hole on the stone slab using a pencil, then carefully cut along the outline with the rotary tool. Make sure to wear appropriate safety gear and work slowly and steadily to avoid damaging the stone slab.
