3. Double-Check: Before cutting, double-check your measurements and the marked line to ensure accuracy.

Securing the Tile

1. Choose a Stable Surface: Work on a stable and flat surface, such as a workbench or a sturdy table.
2. Use Clamps: Secure the tile to the work surface using clamps. This will prevent the tile from moving during the cutting process and reduce the risk of accidents.
3. Protect the Surface: Place a piece of scrap wood or cardboard under the tile to protect your work surface from scratches and damage.

Angle Grinder Tile Cutting Techniques

Dry Cutting vs. Wet Cutting

There are two main methods for cutting tiles with an angle grinder: dry cutting and wet cutting.

• Dry Cutting: This method involves cutting the tile without water. It’s faster and more convenient, but it produces a lot of dust.
• Wet Cutting: This method involves using water to cool the blade and reduce dust. It’s cleaner and safer, but it requires a water source and can be messier.

Which method should you choose?

• Dry Cutting: Suitable for smaller projects and when dust control is not a major concern. Always wear a dust mask or respirator.
• Wet Cutting: Recommended for larger projects, cutting harder materials like porcelain, and when dust control is important.

Step-by-Step Guide to Dry Cutting

1. Prepare the Tile: Mark the cut line and secure the tile to the work surface with clamps.
2. Put on Safety Gear: Wear safety glasses, a dust mask or respirator, and ear protection.
3. Start the Cut: Hold the angle grinder firmly with both hands. Position the blade on the marked line and start the grinder.
4. Score the Tile: Gently score the tile along the cut line. This will help prevent chipping. Apply light pressure.
5. Complete the Cut: Gradually increase the pressure and continue cutting along the scored line. Maintain a steady and consistent speed. Don’t force the blade through the tile.
6. Let the Blade Cool: If the blade gets too hot, stop cutting and let it cool down for a few minutes.
7. Clean Up: After cutting, clean up any dust with a vacuum or damp cloth.

Step-by-Step Guide to Wet Cutting

1. Prepare the Tile: Mark the cut line and secure the tile to the work surface with clamps.
2. Set Up Water Source: Have a bucket of water and a sponge nearby.
3. Put on Safety Gear: Wear safety glasses, a dust mask or respirator, and ear protection.
4. Start the Cut: Dip the sponge in water and squeeze it over the cut line to keep the blade and tile cool.
5. Score the Tile: Gently score the tile along the cut line with the wet blade.
6. Complete the Cut: Continue cutting along the scored line, keeping the blade and tile wet.
7. Clean Up: After cutting, clean up any water and debris.

Angle Grinder Tile Scoring Method

Scoring the tile before making a full cut is crucial, particularly when using an angle grinder. This technique involves lightly etching a line along the intended cut path. Scoring helps to:

• Prevent Chipping: By creating a shallow groove, the blade has a guide, reducing the likelihood of the tile surface splintering or chipping during the full cut.
• Ensure Accuracy: The score line acts as a visual guide, making it easier to follow the intended path with the angle grinder, which results in a straighter and more precise cut.
• Reduce Vibration: The initial groove can help to dampen vibrations, leading to a smoother and more controlled cutting experience.
• Reduce Glazing: Scoring helps minimize glaze damage of ceramic tiles.
• Ease of cut: Scoring helps reduce the amount of force needed to make a cut.

To score, run the diamond blade gently along the marked cut line with minimal pressure. The depth of the score should be shallow, just enough to create a visible groove. Once the tile is scored, you can proceed with the full cut, following the established score line.

Advanced Techniques

Cutting Porcelain Tile with Grinder

Porcelain tile is much harder than ceramic tile, requiring specific techniques to achieve clean cuts.

• Use a High-Quality Diamond Blade: Choose a diamond blade specifically designed for cutting porcelain. Continuous rim blades are generally preferred for their smooth cutting action.
• Wet Cutting is Essential: Always use wet cutting to keep the blade cool and reduce dust. Porcelain generates more heat than ceramic when cut.
• Score the Tile Deeply: Score the tile multiple times along the cut line to create a deeper groove.
• Take Your Time: Cut slowly and steadily, allowing the blade to do the work. Avoid forcing the blade through the tile.

How to Miter Tile with Angle Grinder

Mitering tile involves cutting the edges at a 45-degree angle to create a seamless corner. This technique is commonly used for creating decorative borders and trim.

1. Mark the Miter Angle: Use a protractor or miter square to mark the 45-degree angle on the tile.
2. Secure the Tile: Secure the tile to the work surface with clamps.
3. Set the Angle Grinder: Adjust the angle grinder so that the blade is at a 45-degree angle.
