These jaws are used to hold pen blanks for drilling. The two jaws have recesses to hold the pen blank at the corners. They are self centering so the blank can be easily drilled using a key chuck and drill set in the tail stock of the lathe. They can hold larger pieces for drilling as well. The jaws are 1-3/4" deep.
