The Stronghold Chuck is operated by a key. Key operation provides two major advantages:
One handed operation
Solid holding power
5 to 1 ratio assures powerful clamping
The body diameter of this chuck is 4½" (the largest currently available in our chuck family).
Note: If your lathe is less than a 16" swing, we recommend our Talon Chuck.
The following features are standard on our chucks:
nickel plated body
hardened base jaws
manganese phosphate coated scroll
