Hi, I need to drill a hole (0.5" dia) thru my 6" thick wall (i believe
its called dry wall). I have a B&D power screw-driver/drill, and
yesterday I also purchased a long 0.5" dia drill. I intend to use these
to drill the hole. The issue I have is this:
- How do I ensure that I dont drill into an AC wiring? Is there a
simple/inexpensive way to detect AC wiring? If possible, I'd like to
avoid purchasing an AC finder specifically for this project, bcoz its
unlikely I'd need it again. Or is there an inexpensive one out there
that I can purchase? (FYI: I live in the San Jose area in California)
There is an electrical outlet near the place I wish to drill, so I do
plan to remove its faceplate and visually try to see which way the wires
go. But that still doesnt give 100% gurantee. There could be other
wiring thats running thru.
If you hit the conduit or flexible shielding, you will know. It is not so
easy to penetrate metal by accident. Don't be so scared of electrical
PS there is no such thing as 6" thick drywall. Most of the wall is
hollow. You can make a hole in the front surface, and look inside. If
it's all clear, continue to the back surface, assuming you have a 6" long
Now if by some chance there is conduit behind the point at which you
drilled, you will have to learn how to patch the hole.
Hmmm conduit behind the drywall? I don't think so.
Normally, once you've drilled through the thickness of the drywall (less
than an inch), stop drilling, there will be empty space or insulation. You
don't have to drill any further. Once the hole is made, you can see if there
is any cable directly behind the drywall. If you hit a stud, normally a
metal plate should protect any cable in that area, or the cable is passed
through a hole in the stud a couple of inches from the drywall. But if you
need 6 inches, you may need to be careful about cables behind the insulation
or passing through the stud.
Why do you need 6 inches depth anyway? Maybe we could help you out further
if we knew why your hole needs to be so deep.
