After almost 2 months in Stage 1 (rotary tumbler), I still have some rocks that have pits, vugs, etc. I can't afford a rock saw and I'm not a DIYer. I'm wondering if a typical Bench Grinder, like the ones they sell at Sears, Home Depot, etc, could do the job of removing unwanted flaws on rocks? Or could an inexpensive Tile Saw work?
I'm not looking to cut slabs, just want to speed up the Stage 1 process by getting rid of pits before I even start tumbling.
Thanks!

I would think a 7" tile saw and a good blade would work for cutting through pits and vugs. Or you could possibly use a hammer and chisel to break them at the pits.

johnnymac1969 DON'T use a bench grinder. The bearings will get chewed up by the rock dust. More importantly the dust, when breathed, WILL cause health issues. A tile saw is a good option for going in on the cheap. That's what I did with my limited budget. You can cut rocks with it or grind them using the edge of the blade.

yep and beside speed and dangerousness of trying to hold a rock up to those rpm you would need a wheel Silicon Carbide wheel that would cut rock most bench grinders only use albumin oxide wheels fairly useless on rock
tile saw got to be the best bet...
