Porcelain Tiles are difficult to cut and can break easily, so you need to use the right tools and the right cutting method to avoid chipping.
Why do porcelain tiles break easily when cut
The main reasons porcelain tiles are difficult to cut are their hardness and brittleness.
This high hardness makes them resistant to scratches and abrasion, but it also makes them difficult to cut, requiring high pressure and a sharp, harder blade.
Although hard, porcelain tiles lack the toughness and ductility of metal or wood. They are a typical brittle material. When the cutting pressure is incorrect or micro-cracks are introduced, the tile can break uncontrollably, resulting in chipping, shattering, or even complete breakage.
The best blade for cutting tiles
Hot-pressed sintered diamond saw blades are the best saw blades for cutting porcelain tiles. These continuous-edge diamond blades offer a very smooth cutting surface, minimal chipping, and the highest cutting accuracy. The toothless design reduces vibration and ensures a smooth, clean cutting edge.
How to cut porcelain tiles without chipping
Marking and marking: Use a marker to mark the desired cut on the tile. Use a tool to mark the tile. Taping: Apply cloth-based tape on both sides of the cut line to enhance surface tension and prevent chipping.
Notching a tile: Start cutting from the edge of the tile. Drill holes (notching) the cut edge to reduce pressure on the tile during cutting and prevent cracking.
Smooth cutting: Cut at a slow, even, and steady pace.
Wet cutting tile: Wet cutting is the best method for cutting tile. Dry tile is more prone to chipping. Wet cutting with water helps reduce breakage and creates a cleaner cut. It also extends the life of the saw blade, cooling it and protecting it.
FAQ about cutting ceramic tiles:
Q: Why is wet cutting better than dry cutting?
A: Water cooling immediately lowers the temperature at the contact point between the saw blade and the tile, reducing micro-cracks caused by thermal stress. It also flushes away debris, ensuring a smooth cut.
Q: How do I remove burrs from the cut edge?
A: Use a diamond flap disc or sandpaper to polish along the cut edge.
Q: What if my manual cuts aren’t always straight?
A:Check the scoring wheel for wear (if necessary). When scoring, hold the ruler close and apply even pressure. Before breaking, ensure the support point is precisely aligned with the cutting line.
Q: Should I drill tile quickly or slowly?
A: Cut slowly, evenly, and steadily, as tile is very hard and easily chipped. Work carefully, maintain even pressure, and cut slowly.
