There are drill bit skid marks, so, in theory, it might be possible to build some sort of a model (of a drill held by a human hand) and then see under which conditions these skids marks _are_ possible. But that's without considering that the simplest explanation is usually the right one and the at-orbit sabotage is just not that.

Presumably there's a "breakout" burr on the outside surface of the metal which indicates that the drill bit emerged through that surface.

  That would be very hard to remove evidence.

  This only indicates that the hole was made from one side or the other-- we can't say for sure that just because the hole was drilled from the inside that it was done in orbit.

I wonder if the presence of gravity effects the way holes are drilled on the microscopic level

  The smaller the length scale, the less important gravity becomes (think water glass versus water drop versus fog particle), so my gut feeling is that the answer is no.
