As the title states I'm resorting to cutting my marble tiles with an angle grinder. The grinder and the blade are brand new. I didn't want to spend a lot of money on a wet table saw since all I'm doing is my 9X6 bathroom. I have an 8.5 amp Black & Decker angle grinder, 11,000 rpm, and an appropriate size continuous diamond blade with a max rpm of 15,000 and good with dry/wet use.

I got through about 6in. when let off the power to check the tile out and the blade rattled as it was coming to a stop. The top flange came loose on the angle grinder! I'm afraid to keep going. I've seen people use cut off blades with angle grinders before so I don't really understand what the issue was. Any ideas?

  • It sounds like the cutoff wheel is installed backwards. Admittedly I've done it too.

I'd have to guess that you may have installed it incorrectly, or failed to figure out what "correctly" is for your particular grinder/blade combination. I cut a lot of tile with a dry diamond blade on a grinder, and I do recall that the setup for the thin diamond blade was different than for a standard thick grinder blade, though I can't recall how it was different without the thing in front of me.
