The three-jaw scroll chuck will automatically self-center the workpiece. It has hardened steel external jaws that hold the workpiece on the outside diameter of the part. An extra set of jaws is included for holding larger workpieces on the inside diameter of the part.

The four-jaw chuck has hardened steel jaws that must be independently adjusted to center the workpiece. Each jaw can be removed from the chuck body and reversed for clamping odd-shaped workpieces.

If either chuck cannot hold your workpiece, the cast-iron faceplate has slots for T-bolts that hold standard or cus- tom clamping fixtures. With the correct clamping hard- ware, this faceplate will hold non-cylindrical parts such as castings.

Both chucks and the faceplate are removed and installed the same way.
