Step 3: Drill Through the Wall
NOTE: The 12" x 1 ¼" Flat Tip Drill Bit supplied with this kit
is designed to drill through inside drywall, wood paneling,
plywood, wood studs, and insulation panels; and outside
wood, vinyl, aluminum, hardy plank, and all other non-masonry
materials. If you need to drill through masonry materials such
as brick, concrete block or poured cement, we recommend
that you purchase a 1 ¼" masonry drill bit or other drill bits
suited for the type of wall you have. Other adjustments in the
hole-cutting process may be needed in drilling through the
many other wall types, including lathe and plaster. Otherwise,
follow all installation steps as outlined below.
1. Drill from the inside wall to the outside.
2. If another person is available, you may ask them to help you
at this point.
3. On the inside wall, center the pointed tip of the 12" flat drill
bit on your pencil mark, level the drill parallel to the floor and
keeping the drill bit level to the floor throughout, slowly and
steadily apply firm pressure as you drill straight through your
interior drywall or paneling. THEN STOP.
4. With your drill bit through the first layer of wallboard, with
the drill stopped, probe the interior of the wall for any
electrical, water or waste pipes that would be in your direct
path through the wall. Finding none, pull the drill bit back
toward the interior wall, and then CONTINUE at high RPM.
5. When the drill makes contact with any insulation, move the
drill forward very slowly at high RPM to make sure the sharp
drill bit has a chance to cut through the insulation gradually
without snagging. Forcing the drill bit through the insulation
quickly may cause it to snag.
6. Once the drill bit hits the outside wall, apply steady pressure
until just the tip of the bit breaks through.
7. Tell your helper to watch the outside wall, to signal you
when the tip of the bit first emerges. Then stop the drill and
slowly back the drill bit out of the inside wall.
Reliance Controls is not responsible for damage caused to wiring or
piping inside walls caused by drilling.
Step 4: Shape the Hole on the Outside Wall
1. From the outside of the house, using the 1 ¼" flat bit drill,
center the pointed tip of the drill in the hole that was created
when you first penetrated the outside wall.
2. Keeping your drill level and on high RPM, carefully and
slowly drill through the harder inside wall layers only.
3. Vary the drill speed as needed to avoid cosmetic damage
until you have a clean 1 ¼" hole.
