Description: |
| The sliding jaws of the chuck are moved by cam-shaped openings of a disk-shaped head. Screws in the side of the head fit in notches of the adjusting disk to hold the adjustment.
The specifications are vague as to the intended use for this adjustable chuck. It looks like it would make a nut wrench or hold small tools. |
