  • A straight edge or a guide rail
  • A pencil or marker
  • A measuring tape or ruler

Now that we’ve covered the tools let’s move on to the process of sawing porcelain tiles with a circular saw.

Step 1: Prepare the tile

Before you start cutting, you need to mark the tile with the cutting line. Use a straight edge or a guide rail to ensure the line is straight and accurate. You can also use a pencil or marker to make the line more visible.

Next, measure the size of the tile and mark the cutting line on the tile. Make sure the cutting line is at least 1/8 inch away from the edge of the tile to prevent chipping. Once you’ve marked the tile, you’re ready to move on to the next step.

Step 2: Set up your work area

You need to set up your work area before you start cutting the tile. Find a flat surface, such as a workbench or table, and place the tile on it. Make sure the tile is secured and doesn’t move during the cutting process.

You also need to prepare a water spray bottle to keep the tile cool during cutting. Porcelain tiles generate a lot of heat when cut, which can cause the tile to crack or break. Spraying water on the tile during cutting helps reduce the heat and prevent damage.

Step 3: Adjust the saw

Once your work area is ready, you need to adjust the saw to the correct depth. The depth of the blade should be at least 1/8 inch deeper than the thickness of the tile. For example, if the tile is 3/8 inch thick, the blade’s depth should be at least 1/2 inch.

To adjust the saw’s depth, turn off the saw and loosen the blade adjustment screw. Adjust the depth of the blade using the depth scale on the saw. Make sure the blade is secure and tight before you start cutting.

Step 4: Start cutting

Now it’s time to start cutting. Turn on the saw and let it reach full speed before you begin cutting. Hold the saw firmly and slowly guide it along the cutting line. Keep the saw blade aligned with the cutting line to ensure a straight cut. Make sure the water spray bottle is within reach and spray water on the tile as you cut.

Cutting porcelain tiles generates a lot of dust, so make sure you’re wearing safety goggles and a mask to protect your eyes and lungs. You should also wear gloves to protect your hands from the sharp edges of the tile.

Step 5: Complete the cut

Once you’ve cut the tile along the cutting line, turn off the saw and let the blade stop spinning. Carefully remove the tile from the workbench and inspect the cut edge. If the cut is not clean or there are rough edges, use a sandpaper or diamond abrasive pad to smooth out the edges.

Step 6: Repeat the process

If you need to cut more tiles, repeat the process from step 2 to step 6. Make sure you adjust the depth of the saw blade for each tile since they may have different thicknesses.
