What size wheels were you using? Were they the cutoff wheels?

Standard 4.5". They were marked "Masonary" - I guess they were
cut-off wheels...

Ok - never used those. You just got me curious when you said you went
through them quickly. Maybe that's just the nature of a masonry
wheel. I try to avoid masonry...

I didn't say I went through them "quickly." One wheel for every ten tiles
didn't SEEM excessive.

And, since these were "used" tiles (free from Craigslist) I used the same
wheels to remove the quickset from the backs.
