Safety Precautions

Before diving into the cutting process, it is crucial to prioritize safety. Here are some essential safety precautions to keep in mind while cutting granite tiles with a wet saw:

Protective Gear: Wear safety goggles, ear protection, and gloves to safeguard yourself from any potential hazards.

Ventilation: Work in a well-ventilated area or wear a respirator to avoid inhaling harmful dust particles.

Sturdy Work Surface: Ensure your wet saw is placed on a stable and level workbench or table, minimizing the risk of accidents.

Familiarize with the Wet Saw: Read the manufacturer’s instructions thoroughly and understand the functionality of the wet saw before operating it.


Choosing the Right Diamond Saw Blade 

The diamond saw blade is a critical component of the wet saw, designed specifically for cutting hard materials like granite. Here are a few factors to consider when selecting the appropriate diamond saw blade:

Blade Size: Ensure that the blade size matches the wet saw’s specifications, allowing for a secure fit and efficient cutting.

Diamond Concentration: Higher diamond concentration on the blade indicates better cutting performance and longevity.

Blade Type: Opt for a continuous rim diamond blade for smooth and clean cuts on granite tiles.

Wet or Dry Cutting: Since we are using a wet saw, choose a blade specifically designed for wet cutting, as it requires water for cooling and lubrication.


Preparing the Wet Saw

Proper preparation of the wet saw is essential for efficient and precise cutting. Follow these steps to set up the wet saw:

Water Supply: Fill the wet saw’s water reservoir according to the manufacturer’s instructions. Ensure a constant water flow to the blade during cutting to prevent overheating and reduce dust.

Adjusting the Blade Height: Adjust the wet saw’s blade height to the desired cutting depth, considering the thickness of the granite tile.

Fence or Guide: Position a fence or guide on the wet saw’s table to ensure straight and accurate cuts.

Test Run: Before starting the actual cutting process, perform a test run on a scrap piece of granite tile to familiarize yourself with the wet saw’s operation and blade alignment.

Now that everything is properly set up, let’s move on to the cutting process itself. Follow these steps to cut granite tiles with a wet saw:

  1. Marking the Tile:Measure and mark the desired cutting line on the granite tile using a pencil or marker. Ensure accurate measurements and use a straight edge or a square for precise markings.
  2. Positioning the Tile:Place the granite tile on the wet saw’s table, aligning the marked cutting line with the wet saw’s blade.
  3. Slow and Steady Feed: Start the wet saw and gradually push the tile towards the blade, applying steady and even pressure. Avoid forcing the tile too quickly, as it may cause chipping or damage to the tile.
  4. Use a Push Stick:When the tile becomes smaller in size, use a push stick or a scrap piece of wood to guide the tile and maintain a safe distance from the blade.
  5. Cooling and Lubrication:Ensure that the water supply to the wet saw is consistent, providing cooling and lubrication to the diamond blade throughout the cutting process. This prevents overheating and extends the blade’s lifespan.
  6. Repeat the Process:Repeat the cutting process for each granite tile, ensuring accurate measurements and alignment for uniform cuts.


Finishing Touches and Safety Tips

Once the cutting is complete, it’s essential to pay attention to finishing touches and additional safety measures:

Smooth Edges: Use a tile file or a sanding stone to smooth any rough edges or sharp corners on the cut granite tile.

Clean-Up: Thoroughly clean the work area, removing any granite dust or debris.

Blade Maintenance: After completing the cutting process, turn off the wet saw and clean the diamond blade. Follow the manufacturer’s instructions for proper blade maintenance to ensure its longevity.

Disposal: Dispose of the granite tile remnants and any waste material safely and in accordance with local regulations.

Store the Wet Saw: After completing your project, store the wet saw in a dry and secure place to prevent any damage or unauthorized use.



Cutting granite tiles with a wet saw equipped with a diamond saw blade is an effective way to achieve precise and clean cuts. By following the step-by-step instructions and safety precautions outlined in this guide, you can confidently tackle your granite tile cutting project. Remember to prioritize safety, maintain the wet saw and diamond blade, and take your time to ensure professional-looking results. With practice and proper technique, you’ll be able to handle granite tile cutting projects with ease.
