How to Drill More Faucet Holes on a Silestone Countertop After Installation
Silestone is a type of hard quartz used in countertops. Unlike soapstone and some other materials, Silestone is dense and hard to penetrate. This means a regular drill bit or paddle bit will not go through the countertop. Cutting a faucet hole in Silestone after it has been installed will require a diamond drill bit and water to cool the bit and countertop to avoid cracking or damaging the Silestone. Does this Spark an idea?

Place masking tape on the Silestone countertop. Place the drill bit onto the masking tape and draw a circle around the bit with a marker for a visual reference.

2
Place a circle of modeling clay around the area three times greater than the size of the hole being drilled. Form a circular "wall" about 3 inches high of modeling clay on the Silestone to create a "pool" in which water can be poured to cool the bit as you drill. Fill the modeling clay pool with water. Place an empty bucket under the countertop to catch the water and hole debris.

Place your diamond drill bit into the marked circle on the masking tape and begin to drill through the Silestone carefully. Do not apply too much pressure or the bit may slip and damage your countertop. Continue to drill through the Silestone with the diamond bit until the hole is cut.
