Granite worktops are renowned for their durability, elegance, and timeless appeal. However, installing a granite worktop often involves cutting it to fit your kitchen’s layout. Cutting granite may seem like a daunting task, but with the right tools, knowledge, and precautions, it’s a manageable DIY project. In this comprehensive guide, we’ll walk you through the steps of cutting granite worktops, providing valuable insights, tips, frequently asked questions, and external resources to ensure your project is a success.


Step-by-Step Guide: Cutting Granite Worktops

Step 1: Safety Precautions

Before you begin, ensure you have the necessary safety gear. This includes safety glasses to protect your eyes, a dust mask to shield against airborne particles, and ear protection due to the noise created during cutting.

Step 2: Measure and Mark

Measure the granite worktop for the desired cut and mark the cutting line clearly. Use a pencil or masking tape to make the line visible.

Step 3: Set Up the Work Area

Choose a well-ventilated workspace, preferably outdoors, to minimise dust and ensure a safe cutting environment. If working indoors, use proper dust containment measures.

Step 4: Choose the Right Tools

Select the appropriate cutting tool based on your specific needs. A circular saw with a diamond blade is suitable for straight cuts, while a wet tile saw is ideal for more intricate cuts. Ensure the tool is in good working condition.

Step 5: Cut Slowly and Steadily

Start cutting the granite worktop slowly and steadily along the marked cutting line. Maintain a consistent cutting speed and avoid applying excessive pressure, which can cause chipping.

Step 6: Keep the Blade Cool

If you are using a dry-cutting tool, it’s crucial to keep the blade cool to prevent overheating and potential damage. You can do this by applying water or a cooling agent to the blade during the cutting process.

Step 7: Clean and Smooth

Once the cut is complete, clean the granite surface of dust and debris. To achieve a polished edge, use a diamond abrasive pad to smooth any rough edges or imperfections.

Cutting granite worktops can be a challenging task, but with the right tools, safety precautions, and knowledge, it’s a feasible DIY project.

Proper planning, including accurate measurement and marking, will ensure a clean and precise cut. The choice of cutting tools, whether a circular saw with a diamond blade or a wet tile saw, should align with the complexity of the cut and your equipment.

Remember to maintain a slow and steady cutting pace, and if you’re using a dry-cutting tool, keep the blade cool to prevent overheating. After the cut is complete, take the time to clean the granite surface and smooth any rough edges for a polished finish.
