Question about using a cheap angle grinder to cut a stubborn piece of granite
Everyone at the rock club said you need a wet saw or a diamond blade on a big tile saw for any decent slab work. I had this piece of Barre granite, about 2 inches thick, that I just needed a small corner off of. My wet saw was broken, so I grabbed a $30 angle grinder from the hardware store and a cheap diamond wheel. I held it steady, made a shallow score line, and kept spraying it with a water bottle. It took me maybe 15 minutes, but I got a clean break with no chipping. Has anyone else had luck with a simple grinder for small cuts, or was I just lucky?

Yeah, Barre granite is tough, but saying it's too hard for a grinder isn't totally right. The key is keeping it cool, which you did with the water bottle. A cheap diamond blade on a grinder can work for small jobs if you go slow and let the tool do the work. It's not the right choice for big slabs, but for a quick corner cut, it's a solid fix. You weren't just lucky, you used the right method for a small task.

Exactly. Slow and steady wins the race.
