SAFETY FIRST!
Wear gloves, safety goggles and head protection when drilling. Avoid nails, they ruin bits and they
can cause injury. Pay particular attention when using “hole-hogs” and other powerful electric drills;
the torque of the drill when suddenly stopped by a nail can break a strong person’s wrist.
DRILLING
Use a bit that is large enough for the cables you plan to run. An auger bit is the preferred bit for
rough-in wiring. It will actually pull itself through the wood, so that the drill motor, not you, does
most of the work.
Always drill the holes in the center of the stud. If you have to notch the stud or drill the hole closer
than one inch from the edge of the stud, protect the cable with a nail plate.
When drilling holes in ceiling joists, drill in the center of the joists and try to locate the hole near
the end of the joist. DO NOT drill through a “gluelam” or any load bearing beam without the
direction of your contractor.
Try to line the holes up perfectly, because it makes pulling the cable much easier. A good technique
is to snap a chalk line across the face of the studs or against the bottom of the ceiling joists. Then
work backward so that you can always see the holes you have already drilled. Paying careful
attention to this will save you a lot of time later!
