Cutting porcelain tile is necessary to install it in certain areas. Tiles that go around piping, toilets, towel racks or a toilet paper dispenser have to be shaped in order to accommodate the fixtures. Porcelain tiles have a very low porosity level which makes them extremely tough and hard to drill. However, you need not despair. With the help of a wet saw and diamond core drill bit, you can successfully cut your tiles into the required shapes without chips and cracks.
What You’ll Need
Diamond core drill bits
Step 1 – Set up the Saw
Select a level, stable site and set the saw on it. The saws usually come with a pan underneath to hold the water as you cut. Fill the pan with water up to the required level. The water helps to cool the edge of the blade as it rotates. Be sure to obtain a work table or a flat surface where you can spread the tiles before you cut.
Step 2 – Mark the Tiles
Spread the tiles on the table with the unglazed side facing up. Use a grease pencil to mark curves and angled cuts on the tile surface.
Step 3 – To Cut Curves
Turn on the machine and align the cutting line against the saw blade. Hold the tile with your hands, on each side of the blade. Gently push the tile into the blade to allow the blade to begin to cut into the tile. Push the tile steadily into the blade. Keep your eye on the cut line to guide the cut until you complete your curved cut.
Step 4 – Angled Cuts
It is best to cut the tile up to the end of the marked line for corner cuts. Turn the tile over and make the second cut line till it meets the first line. This creates a perfect corner cut. It is easier to cut corners in 2 steps rather than attempt to make the cut in one single motion.
Step 5 – Circular Cuts
Attach masking tape on the unglazed side of the tile. The tape helps to contain the drill bit which allows you to drill holes efficiently through the tile. Draw the circle on the tape with a pen. Dip the bit into oil to keep it cool. Place the bit at one point of the circle and drill a hole into the tile. Begin at a low speed and gradually build up the speed until you drill through the tile. Dip the bit frequently into the oil as you drill to help keep it cool. Wipe excess oil with a rag. Proceed to drill several holes on the circle at small intervals apart until you’ve punched all around. Remove the tape. Place the tile on a piece of wooden block and hold it with one hand. Take your hammer and gently knock out the circle in the middle until it falls out. It will break along the drilled holes.
Use a masonry file to smooth out the rough edges. You can now proceed to install your shaped tiles wherever they are required.
