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.
