I'd say the middle at the back about an inch or two from the stem will be the least stress area to drill if you're set on doing that. And yeah you'd want to drill a small pilot hole and then angle at 45 for a smooth cable run out the bar.
Edit: do some research on this. If you do it wrong, they're gonna crack, and dentists aren't cheap.
