Drill or notch joist

drilljoists

Followup to another question where I asked about drilling diagonally up into the sole plate and joist (I think I got good answers but realized but didn't get a clear "it's ok to drill through the joists diagonally".

Trying to run coax up the basement. I am learning this desired spot is within the outer 1/3 of the 14ft joist (It's ~4ft in from one of the ends).

Where I need to get to I could drill diagonally up through these two joists or everything I'm reading says it needs to be a notch.

Can you notch this joist in the basement after it's already installed with some sort of oscillating tool or some other method?

tl;dr Stop fretting and run the wire already. :)

A hole is somewhat better than a notch at the edge because the hole leaves a resulting lattice structure, which is more strong and rigid then a joist with reduced height due to the notch. However, if your notch is only as large as the hole would have been, say 5/8", it really doesn't matter much.
