How Should Large Format Tiles Be Cut?

Installing large format tiles can transform the look of a space, adding elegance and a modern touch. However, when it comes to fitting these tiles into smaller or irregular areas, cutting them properly becomes essential. In this article, we will guide you through the process of cutting large format tiles with precision and ease, using tools such as an angle grinder and a diamond saw blade. Let’s dive in!

Tools Needed:

  • Angle Grinder: An angle grinder is a versatile power tool that can be fitted with different attachments, including diamond saw blades. It is ideal for making straight and curved cuts on large format tiles.
  • Diamond Saw Blade:When cutting large format tiles, a diamond saw blade is crucial due to its ability to cut through hard materials effectively. For this task, we recommend using a 7-inch (180 mm) continuous rim diamond saw blade.

Step-by-Step Procedure:

Step 1: Gather Safety Gear

Before starting any tile cutting project, ensure you have the necessary safety equipment. This includes safety glasses, gloves, and a dust mask to protect your eyes, hands, and lungs.

Step 2: Mark the Cutting Line

Measure the area where the tile needs to be cut and mark the cutting line using a pencil or a marker. Ensure that your markings are clear and visible.

Step 3: Set Up Your Work Area

Prepare a stable and flat work surface to prevent the tile from shifting during the cutting process. You can use sawhorses, a workbench, or any other suitable surface. Place a piece of scrap wood or tile underneath the marked area to support the tile during the cutting process.

Step 4: Attach the Diamond Saw Blade to the Angle Grinder

Follow the manufacturer’s instructions to attach the 7-inch diamond saw blade securely to the angle grinder. Make sure it is tightened properly to avoid any accidents during operation.

Step 5: Wear Safety Gear and Prepare the Tile

Put on your safety glasses, gloves, and dust mask before proceeding. Place the large format tile on the work surface, aligning the marked cutting line with the blade’s path.

Step 6: Make the Cut

Start the angle grinder and position the diamond saw blade along the cutting line on the tile. Gently apply pressure and move the angle grinder along the marked line, allowing the blade to cut through the tile. Ensure a smooth and continuous motion throughout the cut, avoiding any sudden or jerky movements.

Step 7: Cooling and Lubrication

Large format tiles can generate a significant amount of heat during the cutting process, which can damage the blade or tile. To prevent overheating, periodically cool the blade by dipping it in water or using a coolant spray. This will help maintain the diamond blade‘s effectiveness and extend its lifespan.

Step 8: Complete the Cut

Continue cutting along the marked line until you reach the end. Be cautious when approaching the end of the cut to prevent any chipping or damage to the tile. Maintain a steady hand and a controlled motion until the cut is complete.

Step 9: Smoothing the Edges

After completing the cut, inspect the edges of the tile. If there are any rough or jagged edges, use a tile file or a sanding block to smooth them out. This will ensure a clean and professional finish.

Step 10: Clean Up

Once you have finished cutting the large format tile, clean up the work area. Remove any debris, tile fragments, or dust from the surface and surrounding area to maintain a clean and safe workspace.

Tips for Achieving Accurate Cuts:

To ensure the best results when cutting large format tiles, here are some helpful tips to keep in mind:

  1. Measure Twice, Cut Once: Before making any cuts, double-check your measurements to avoid any costly mistakes. It’s crucial to be precise and accurate with your measurements to achieve the desired fit.
  2. Use a Guide: If you need to make long straight cuts, consider using a straight edge or a tile cutting guide to maintain a steady and straight cutting line. This will help you achieve clean and professional-looking cuts.
  3. Take Breaks: Cutting large format tiles can be a time-consuming task, especially for larger projects. It’s important to take breaks periodically to avoid fatigue, which can lead to less precise cuts. Staying focused and refreshed will help you maintain accuracy throughout the cutting process.
  4. Practice Cutting Techniques: Before tackling your actual tile installation, practice cutting on some scrap tiles of the same material. This will allow you to familiarize yourself with the angle grinder and diamond saw blade, helping you refine your cutting technique and gain confidence.
  5. Use Masking Tape: Applying masking tape along the cutting line can help reduce chipping and protect the surface of the tile during the cutting process. The tape acts as a buffer and provides extra stability, resulting in cleaner cuts.
  6. Consider Tile Orientation: When cutting large format tiles, consider the orientation of the pattern or design on the tile. Make sure to align the cut tiles in a way that maintains the continuity of the pattern, especially if the tiles have a specific pattern or veining.
  7. Work in a Well-Ventilated Area: Cutting tiles can generate a significant amount of dust and debris. Ensure you work in a well-ventilated area or use a dust extraction system to minimize the inhalation of dust particles. This will protect your respiratory health and maintain a clean work environment.

By incorporating these tips into your cutting process, you can enhance the accuracy and quality of your cuts, resulting in a seamless tile installation.


Cutting large format tiles can be a challenging task, but with the right tools and techniques, it becomes much more manageable. By following this step-by-step guide, using an angle grinder with a diamond saw blade, you can achieve precise and clean cuts, allowing you to fit the tiles perfectly into any space. Remember to prioritize safety by wearing the appropriate gear and taking necessary precautions. With practice and patience, you’ll be able to master the art of cutting large format tiles with ease and confidence.
