I'm trying to run some coax cable from a splitter in the attic (accessible) to a room on the other side of the house. Normally one would just worm over to the top of the appropriate wall, drill a hold in that 2x4, drop the cable down and be all ready to hook it up to a wall plate.

But in my case, the top of that particular wall is not accessible - there is an impassible barrier in this very low-roofed attic. Nonetheless, if I could drill the hole from inside the wall, I could push a snake/fish up through it, and hopefully reach the accessible attic area. Then I'd pull the cable (and a backup twine) back down by retracting the snake.

First up, does this sound like the right plan at all? Second, what's the best way to drill up like that? I could cut a hole in the wall big enough to put my entire drill into, but is there a better way? I also have a Dremel, and they make a flexible exension, but I'm not sure if that could drive a large enough bit through a 2x4.

The good news is, if I do cut into the wall near the ceiling to do this, I can do that from inside a closet, so the subsequent repair doesn't need to be perfect. I could even cover it with an access plate instead of repairing it, in case I wanted to get back in there.

Thanks,
Greg
