Cutting a wide hole for a faucet feels risky because one crack ruins the surface. A diamond hole saw and a guided start make it controllable.
Pick the right diameter
Measure the fixture, then match the saw size. A common 2-1/8 inch diamond tile hole saw fits many faucets and disposal buttons, so confirm the opening before you cut.
Start with the pilot bit
Install the guiding pilot to set the center. It stops the rim from skating across glaze, keeping the hole exactly where you marked it on the surface.
Remove the pilot to finish
Once the ring is scored, take the pilot out with the hex wrench. Finish with a slight wobbling motion so the diamond rim cuts evenly around the full circle.
Keep it cool
Diamond hates heat. Lubricate with water during the cut or dip the bit between passes. Cooler cutting protects the edge and gives you a cleaner hole.
Check the depth
Know your material thickness and the saw's cutting depth. For thick countertops, work steadily and let the rim do the cutting rather than forcing it through.
The bottom line
Size it right, start with the pilot, cool often, and stay patient. That routine turns a scary cut into a clean, confident one.
