Diamond Blades for Porcelain That Won't Chip the Glaze

Diamond blades for porcelain have to do something most stone blades don't: cut porcelain tile without chipping the glaze or cracking a brittle edge. Porcelain runs harder and less forgiving than marble or granite, so we stock vacuum brazed and electroplated blades built for that density, not general-purpose blades pressed into service. Cutting thick porcelain slabs on a bridge saw? Pair these with our bridge saw blades for straight, controlled cuts. Working freehand with an angle grinder? Our turbo blades handle the detail work. Once the cut's made, clean up the edge with wet polishing pads rated for porcelain.

Frequently Asked Questions

+

What's the difference between a vacuum brazed and an electroplated porcelain blade?

Vacuum brazed blades hold their diamond segments longer under heat and pressure, so they cut through more linear feet before wearing down. Electroplated blades cost less upfront and leave a cleaner, thinner kerf, which matters on a visible polished edge. Most fabricators keep both on hand: electroplated for finish cuts, vacuum brazed for volume work.

+

Can I use a regular diamond blade on porcelain tile?

You can, but it's not a good idea. Porcelain's density and brittleness make it chip and crack under a blade built for granite or marble, especially near the edge. A blade made for porcelain uses a finer diamond concentration and a thinner kerf to keep the glaze intact.

+

Do I need a wet saw, or can I cut porcelain dry?

Wet cutting is the standard for porcelain. Water keeps the blade cool and clears away dust that would otherwise clog the diamond segments and cause chipping. Dry cutting works for short cuts with a turbo blade and a grinder, but a bridge saw with water is the safer bet on large format tile.

+

What size blade do I need for porcelain slabs?

Most fabricators run 10 inch to 14 inch blades on a bridge saw for porcelain slabs, and 4 inch to 5 inch turbo blades for handheld grinder work. Check your saw's arbor size and max blade diameter before ordering.

+

Do you ship porcelain blades fast?

Orders over $99 ship free. Call (877) 413-4266 if you need something on a rush timeline for a job.

Optional: Add the standard in-stock fulfillment/shipping timeframe if the product team provides one.

How do I know when a porcelain blade needs to be replaced?

Watch the cut, not just the blade. If you're seeing more chipping along the edge, slower cutting speed, or the segments look glazed over and shiny instead of sharp, it's time to swap it out. Cutting porcelain with a dull blade increases the chance of cracking the tile.
