How to Cut Porcelain Tiles

The key to a smooth, precise cut lies in using the right equipment and following these simple steps:


  1. Measure and mark the tile - Use a measuring tape to measure the length you need to cut on the porcelain tile. Mark the tile with a pencil where you need to cut it.
  2. Prepare the tile saw - Fill the reservoir of the tile saw with water to keep the blade cool and prevent dust from flying around. Adjust the blade depth to match the thickness of the porcelain tile.
  3. Put on safety gear - Wear safety glasses and a dust mask to protect yourself from dust and debris.
  4. Cut the porcelain tile - Turn on the tile saw and slowly push the tile towards the blade. Let the blade do the cutting and avoid applying too much pressure. Use a smooth and steady motion to guide the tile through the blade.
  5. Clean the tile saw - Turn off the tile saw and clean up any dust or debris that has accumulated. Empty the water reservoir and wipe down the saw.
  6. Check the cut - Inspect the cut to ensure it's clean and precise. If necessary, use a diamond file or sandpaper to smooth out any rough edges.

FAQs About How to Cut Porcelain Tile

What is the best blade for cutting porcelain tiles?

The best blade for cutting porcelain tiles is a diamond blade. Diamond blades are specifically designed to handle the hardness and density of porcelain tiles, providing clean, precise cuts without chipping. Look for a high-quality diamond blade that is rated for wet cutting to minimize dust and keep the blade cool during use.

Can I cut porcelain tiles without a wet saw?

Yes, you can cut porcelain tiles without a wet saw, but it's not ideal for every situation. Manual tile cutters, handheld tile saws, or even angle grinders equipped with a diamond blade can be used for smaller or less precise cuts. However, for large projects or when you need precise, straight cuts, a wet saw is the best tool due to its accuracy and ability to minimize tile breakage and dust.

How can I avoid chipping when cutting porcelain tiles?

To avoid chipping when cutting porcelain tiles, follow these tips:

  • Use a high-quality diamond blade specifically designed for porcelain.
  • Ensure your tile is securely fastened and doesn’t move during cutting.
  • Cut slowly and steadily, allowing the blade to do the work without forcing it.
  • Use water to cool the blade and reduce friction, which helps prevent chipping.
  • Score the tile first if you're using a manual cutter, then snap it along the scored line.

How can I cut small pieces of porcelain tile?

Cutting small pieces of porcelain tile requires precision. Use a wet saw with a fine-toothed diamond blade for the best results. If the pieces are very small, a tile nipper can be helpful for making minor adjustments. Always make sure to wear safety goggles and gloves to protect yourself from sharp edges and flying debris.

Can I use a regular saw blade to cut porcelain tiles?

Using a regular saw blade is not recommended for cutting porcelain tiles. Regular saw blades are not designed to handle the hardness of porcelain and will quickly become dull or even break, leading to poor cuts and potential damage to the tile and the tool. Always use a diamond blade specifically designed for cutting porcelain tiles for the best results.
