Marking the Cut Line

1. Measure the tile: Use a measuring tape or ruler to determine the desired cut length.
2. Mark the tile: Use a pencil or marker to draw a clear and precise cut line on the tile’s surface. For curved cuts, use a template or freehand sketch.
3. Double-check: Ensure the cut line is accurate before proceeding.

Securing the Tile

1. Choose a stable surface: Place the tile on a flat, stable surface, such as a workbench or a piece of plywood.
2. Use clamps: Secure the tile to the surface using clamps. Make sure the clamps don’t obstruct the cut line.
3. Consider a cutting mat: A rubber or cork cutting mat can provide extra grip and cushioning.

Cutting Techniques: Achieving Precision

There are two primary tile cutting techniques angle grinder : dry cutting and wet cutting.

Dry Cutting

Dry cutting is the most common method, but it produces a lot of dust.

1. Equip yourself with the necessary safety gear: Safety glasses, dust mask/respirator, and ear protection are essential.
2. Start the angle grinder: Hold the grinder firmly with both hands and start the motor.
3. Scoring the Tile: Before making a full cut, scoring tile angle grinder helps prevent chipping. Gently run the blade along the cut line, applying light pressure.
4. Make the cut: Slowly guide the blade along the cut line, maintaining a steady pressure. Avoid forcing the blade, as this can cause it to bind or break.
5. Follow-Through: Once the cut is complete, release the power switch and allow the blade to come to a complete stop before setting the grinder down.

Wet Cutting

Wet cutting tiles angle grinder significantly reduces dust and cools the blade, resulting in cleaner cuts and extending the life of the disc.

1. Set up a wet cutting system: You can use a commercial wet tile saw or create a simple DIY system. A DIY system involves a sponge, a bucket of water, and a way to deliver water to the blade.
2. Keep the blade wet: Continuously apply water to the blade during cutting. This can be done by dipping the blade in water, using a sponge to wet the tile, or using a pump system.
3. Cut slowly: Wet cutting can be slower than dry cutting, so be patient and maintain a steady pressure.
4. Clean up frequently: Remove any slurry or debris that accumulates on the tile’s surface.

Cutting Ceramic Tile with Angle Grinder

• Use a diamond blade designed for ceramic tiles.
• Score the tile before making a full cut to minimize chipping.
• Avoid applying excessive pressure, as ceramic tiles can be brittle.

Porcelain Tile Cutting with Angle Grinder

Porcelain tile angle grinder cut requires a high-quality diamond blade specifically designed for porcelain.

• Use a continuous rim diamond blade for the cleanest cuts.
• Wet cutting is highly recommended to keep the blade cool and reduce chipping.
• Take your time and apply steady, even pressure.

Cutting Curves and Intricate Shapes

1. Draw the curve: Use a template or freehand sketch to draw the desired curve on the tile.
2. Make relief cuts: Make a series of short, straight cuts along the curve, removing small pieces of tile.
3. Smooth the curve: Use the angle grinder to smooth out the curve, removing any sharp edges or corners.
