2. Measure and Mark the Hole

Start by measuring the diameter of the hole needed for your fixture, whether it’s a faucet or any other accessory. Use a measuring tape to determine the precise size. Once measured, mark the spot on the granite surface where the hole will be drilled using a marking tool or a grease pencil.


3. Provide Support for the Granite Surface

To prevent the granite from cracking during the drilling process, it’s crucial to provide adequate support. You can achieve this by placing a piece of duct tape over the marked area and labeling the measurements. Alternatively, place stone scraps on both ends of the hole to cushion the impact of the drill.


4. Choose the Right Drill Bit

Select a diamond drill bit that matches the diameter of the hole you need. Diamond drill bits are specifically designed to cut through hard materials like granite with precision and minimal risk of damage.


5. Begin the Drilling Process

With all preparations in place, it’s time to drill a hole in granite. Start by positioning the drill at a slight angle to the marked spot. As you begin drilling, gradually straighten the drill to create a clean and precise hole. Apply steady but gentle pressure, allowing the diamond drill bit to do the work.

Pro Tip: 

Keep the drill bit and the surface of the granite lubricated with water to minimize heat and reduce the risk of chipping or cracking.

By following these steps, you can successfully drill a hole in granite for various installation purposes, ensuring a secure and professional finish.
