If you're lucky, the flooring is not yet down. No matter what type of
drill bit you use, drill only half way down and then flip the board over
and finish the cut. This will avoid splintering as the bit completes
the cut.

But, over time, the hole won't stay that way. Consider an ordinary hole with
a plastic, cable access, shim/plug.
