    Those are mandrils, they are slightly tapered cylinders used for holding things like gear blanks or other circular pieces with a center hole between centers on a lathe. Idea is you press the workpiece on the taper (usually only 1 or 2 thousands) until it's firm and then turn your work. (sigh) I bought a complete set years ago when I set up my shop and have never had a workpiece with a hole that was exactly the right size to use them....

    Actually, they're mandrels. The other is a monkey.

    There should be numbers stamped on the ends, like 0.4995 and 1.0005 on each mandrel.

    They aren't mandrels - they must be called persondrels...
