I recently acquired an inexpensive set of mini drill bits and handle from Amazon, the smallest bit yielding about a 0.4mm hole, which is about right for 4×5 film, though I do have trouble getting such a small hair-thin bit properly positioned into the chuck of the pin vise. Also discovered a very inexpensive lighted scale loupe (in 0.1 mm increments) from JacksToolShed, which makes viewing the size and roundness of a hole much easier.
