To make the faucet mounting hole (if sprayer or
second hole is used), check below to make sure the
drill does not interfere with anything below.
The faucet should be positioned so it empties into
the sink and the spout swivels freely for
convenience. If sink has a hole that can
accommodate the faucet, no drilling is required.
Proceed with mounting the faucet.
Porcelain, Enamel, Ceramic on Metal or Cast Iron:
Precautions must be taken to penetrate the
porcelain through to the metal base to prevent it
from chipping or scratching the surface. There are
several methods that allow ceramic sinks to be
drilled safely and easily.
Method 1:
Tools required:
•
Variable speed drill
•
Relton porcelain cutter tool set
(7/8" or alternative size, 9/16")
•
Plumber's
putty
Procedures:
1. Mark the center for the 7/8” hole.
2. Form shallow putty around hole area and fill
with enough water to lubricate carbide drill bit.
3. Carefully drill pilot hole through all layers. (Use
light pressure and slow speed.)
4. Insert pilot tip of spring-loaded porcelain cutter
into pilot hole.
5. Drill porcelain / enamel using spring loaded
porcelain cutter, making certain a complete ring
has been cut through the porcelain / enamel to
the metal base.
6. Cut away the inner porcelain / enamel disc
down to the base metal. Make certain the
cutter does not touch outer rim of the cut
porcelain / enamel. Continue until the sink has
been completely penetrated.
Note: Always use sharp cutter to eliminate chips.
Method 2:
Tools required:
•
Masking
Tape
•
Variable speed drill
•
1/4” and 7/16” carbide drill bit
Procedures:
1. Locate faucet placement and tape off the area
with masking tape.
2. Using a drill at slow speeds, drill a pilot hole
through the porcelain using a 1/4” carbide
tipped drill. Note: The bits dull in a very short
period of time when used for drilling porcelain
and should be replaced or sharpened
frequently.
3. Cut through the porcelain and base materials
using a 7/16” carbide tipped hole saw at very
slow speeds.
Stainless steel sinks:
Center punch a small indent at the desired faucet
location. (2” flat surface is required, not exceeding
1-1/4” in thickness.) Drill the required pilot hole for
the chassis punch and tighten nut to cut the desired
hole size. Clean up sharp edges.
Recommended tools:
•
Center
punch
•
Variable speed drill
•
High speed drill bits
•
Greenlee chassis punch
•
Protective gloves & eye protectors
