How to Drill a Hole in Sink or Counter-top
1. It is highly recommended that you watch the YouTube video "How to Drill Faucet Holes."
2. Choose a 1/2" 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 it breaks through the slippery surface.
5. Use a 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. Hold the drill firmly and vertically at the slowest speed to prevent the drill bit from slipping
on the counter.
7. Once you break through the smooth surface, swirl the drill a little to evenly apply pressure
in a circle.
8. Be patient and deliberate. It can take 20 – 40 minutes to drill through 1".
Ice Maker Kit
An Ice Maker Kit (part# iSpring ICEK) can be purchased separately to feed RO water to the
refrigerator and get crystal clear ice cubes and great tasting water at ease. It could make the
Drinking Water Faucet unnecessary.
