How to drill a 1” hole in your sink or counter-top
1. It’s highly recommended to watch the YouTube video “How to Drill Faucet Holes” to get
a better understanding of the process. Depending on what kind of countertop you have, you
may want to hire an experienced professional to ensure the hole is drilled correctly.
2. Choose a half inch Diamond Core Bit for granite, and a titanium drill bit for steel. Do NOT
use a hammer drill on natural stone, glass, and ceramic.
3. An indent should be made with a punch on steel before drilling to help guide the bit.
4. Use caution when drilling on a Porcelain sink, as it could be easily chipped. Set drill speed
on slow. Press the bit downward firmly until breaking through the slippery surface. Some
people found it is easier to secure the bit by drilling through a piece of wood that is firmly
pressed on the surface.
5. Use coolant to disperse heat. Choose water for granite, and oil for steel. Use the Water
Suction Cup to hold coolant inside and prevent the drill bit from slipping.
6. Starting at slowest speed, hold the drill firmly and vertically and prevent the drill bit from
slipping on the counter.
7. Once breaking through the smooth surface, swirl the drill a little to apply pressure in a circle
evenly.
Be patient and deliberate. It can take 20 – 40 minutes to drill through one inch.
