Step 2 – Faucet Installation
To simplify its access and installation, we suggest you install the faucet on the rear lip of the sink. It should be evenly
positioned with the sink faucet and spray attachment. Should the spray faucet hole not be available for the installation,
the sink must be drilled.
NOTE:
It is recommended retaining the services of a professional counter top craft person when a hole is needed in
granite or other specialty counter top materials.
Sink Drilling Instructions
Stainless Steel Sink
Porcelain Enamel Sink
Follow these basic guidelines when drilling a porcelain sink:
One proven tool is the Relton porcelain cutter kit when used with a slow speed drill (300-400 rpm).
• Drill a pilot hole through the porcelain and base material with the carbide tip drill.
• Build a putty dam around the drill area. Add enough water to lubricate cutters and reduce cutting noise.
• Insert the porcelain cutter into the drill. Place the drill tip in the pilot hole. Check for free movement.
• Apply light pressure to the cutter tool and start the drill motor at low speed (300-400 rpm). When the initial cut has
been made in the porcelain, speed may be increased. After a complete ring has been cut through the porcelain,
change over to the metal cutter. Avoid contacting the outer rim of cut porcelain when drilling.
CAUTION!
Avoid high drill speed during penetration of porcelain. A single speed drill can be used at a slow
speed by switching it on and off quickly.
• Use a slow speed and light pressure to cut away the porcelain.
• Stop when you reach the metal under the porcelain. Remove the cutter and clean the porcelain chips from the
surface. Continue cutting through the metal.
NOTE:
Ceramic tile counters should be treated like porcelain when penetrating the surface, then treated as metal to
complete the hole with carbide drills. Formica countertops can be drilled with a high-speed wood drill.

Spring Loaded Porcelain Saw
Finish Hole Saw
Penetrate the porcelain to the base
material.
Protect the surrounding porcelain
material.
Use the appropriate tool to drill the
base material.
1. Select and mark the
proper faucet location.
2. Center punch hole to
provide a starting point
for your drill.
3. Drill a 7/8” hole in the sink using a stepped 7/8” drill
bit. If no stepped bit is available, start by drilling
a 1/4” hole. Using this hole as a starting point
progressively drill larger holes. Increase drill size by
1/8” until you reach a 7/8” hole.
