Fellow I know asks what is a pin vise? Could be 2 styles. One uses a screw down collar and an internal collet split 4, 6 or 8 ways. Another uses a fixed collet with 2 jaws and a sliding ring to tighten things. These are used commonly by watchmakers, jewelers, electronics folks when it is necessary to drill a precision hole by hand. Very handy and not expensive. Image below.
