If you want to "curve" a cable, drill a hole, drill another hole meeting the first hole, fish a pull wire through the second hole with a "knitting needle" (a short snake with a sharpened hook), and use the pull cable to get the cable to curve. Using this "curved bit" will seriously weaken the beam.
Drilling Curved Cable Holes Seems Like A Dumb Idea
Here's a video of the 'cured hole' fixture:
One big drawback of this fixture is it isn't adjustable. The demo beam is basically all the tool is good for punching through.
I agree that doing this will weaken a structural beam considerably. Running cable at a right angle without destroying beams is not brain surgery; it just takes time.
Ari's approach using two perpendicular holes makes good sense!
The solution in the video appears to maintain a standard minimum cable bend radius, (3-5x cable width).
Could one based on two perpindicular holes, in a beam that size, do the same?
Agreed though, if the beam falls apart, it doesn't really matter.
