I’ve done the angle grinder thing on a concrete backed tile countertop and it worked okay, and I’ve used to to straighten up a rough edge on a chunk of limestone so I could match it with a frame better. As others have pointed out, you’re not going to get any straighter line than, say, the thickness of a sharpie, and it won’t be polished, but it works.

I think if I were starting from scratch and looking to do it on the cheap I’d try the circular saw with the spray bottle, because you can water cool it easier than the angle grinder, and it’s easier to set up a board to run the saw along the edge of.

However, what got me posting here was rhett’s assertion that an angle grinder is ”...a tool with very little woodworking applications.” I’m just starting to discover the joy of the angle grinder for woodworking. I’ve seen at least one article about building a jig to control one while it’s got one of those chainsaw-tooth like disks on it for cutting the curve on wood chair seats, but recently I’ve been using it with a sanding disk to carve interesting shapes and curves (at least I think they’re interesting…), which I was inspired to try by episode #10 of Andy's art box tutorial.
