Old guy at a trade show in '08 told me to ditch the wire brush for a poly one on newer flue liners.
I thought he was nuts, but after cracking a clay liner in a 2010 build, I switched. Anyone else make that change and notice less dust coming back into the room?

Honestly, does this happen with everything now? Feels like the old way of doing stuff just wrecks newer materials. I had the same thing with a basic drill bit on some cheap bathroom tiles, just shattered them. Makes you wonder what else we're doing wrong because the stuff changed but the advice didn't.

Cheap tiles often need a special bit, not just a basic one.

Yeah the "special bit" thing is real. I learned that the hard way too, like umac71 said. Those cheap ceramic tiles are super brittle. You need a diamond grit hole saw or a spear point bit made for tile, and you have to go slow with no pressure. A regular masonry bit just hammers them to pieces.
