Why does my diamond blade chip porcelain tile, and how do I stop it?
| Cause | Fix |
|---|---|
| Segmented blade on porcelain | Use continuous rim for porcelain; segmented is for concrete and stone |
| Too much rpm | Run at the low end of the blade rating; heat is what chips glaze |
| Dry cut on hard porcelain | Wet cut, or slow steady feed with a water spray |
| Blade wobble | Check the flange and bore (22.23 mm standard); a worn flange makes every cut wander |
Numbers that help: a 105 mm blade should run around 13,000 rpm max; a 125 mm around 12,000. If your grinder is a fixed 11,000 rpm single-speed unit, blade choice matters more than technique.
The mistake people make: buying the cheapest 10-pack and expecting clean porcelain edges. Cheap segmented blades are fine for wall tile and concrete, not for glazed porcelain.
