Specifications

Stainless Steel Sink
• Select the proper faucet location.
• Center punch hole to provide a starting point for your drill.
• Drill a 1/2-inch hole to accept the shank of a 1-1/4-inch Greenlee Hole Punch.
• Insert the punch. Cut the hole by tightening the drive screw.
• Remove any roughness with a file and clean up metal chips.
Porcelain Enamel Sink
Follow these basic guidelines when drilling a porcelain sink:
• Penetrate the porcelain to the base material.
• Protect the surrounding porcelain material
• Use the appropriate tool to drill the base material.
One proven tool is the Relton porcelain cutter kit, PN 00-5916-25, 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.
NOTICE: 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.
