We all know that those tiny drill bits are very flexible and prone to snap when too much torque is transmitted to that thin little shaft.
Cut the bit in half and discard the shank portion. Chuck the remainder of the bit - the part with the point - into your pin vise and drill away. The shorter shaft is less flexible and therefore less prone to break.
For very tiny drill bits, I discard the upper two-thirds and drill with the remaining point-end-stub. (*note: some visual adjustment by the driller is required!)
Yes, Virginia...size does matter.
