I need to install some coax in a peer and beam house. Someone told be I
need some sort of expensive right angle drill bit. I don't want to drill a
big hole in the wall, just one large enough to run the coax through. What
do I need exactly to drill through the drywall and down through the floor
behind the drywall?
I'm assuming that you are referring to construction where there is a
basement or crawl space underneath? If so the easiest way I've found is
to cut a standard outlet opening to fit an old-work plastic box and then
to use a flexible installer's bit inserted vertically into the hole and
then to drill straight down. Install the box after the hole and cable
are finished. Installer's bits are available in a wide range of lengths
but I've settled on a 4-foot bit as being able to do almost anything I
normally need. I guess the only exception would be to drill upward from
standard outlet height into an attic space (but I'm sure that somebody
makes a bit that will do it).
If you were very good and very lucky then you _might_ be able to fish
wires that way. I did video and audio and alarm and network and
communications wiring for more years than I care to think about. Over
the decades I learned that things always went better when I allowed
myself at least an even chance of pulling off the install before I
started considering making a noose from the wires and ending it all.
But why is it that a neatly-installed standard box with a faceplate
(which could even be camouflaged in whatever color or finish you prefer)
is so undesirable? Surely you must have power outlets and switches in
the rooms too.
I have a 6 foot bit (which is going dull, and I'm not good at
sharpening bits), but from the attic what works in my house is to
start in the unfinished attic where the walls below are visible
between the sections of sheetrock and drill just through the top
plate. More helpful than normal to have someone else downstairs to
grab the wire. In one case I had to recruit my mother's husband.
Unless you make a cute round hole**, you're going to need to do
something to finish it.
**Maybe you could buy or borrow some of that arthroscopic surgical
equipment they have. Hmmm. I think arthroscopic is just for joints
but they also do gall bladders etc with that stuff. Hmmm, even then,
I'm not sure you can get the plaster to grow back like skin etc. does.
