One Way Stronghold Chucks are a heavy duty chuck that is designed for large lathes (16" swing or greater) to provide maximum gripping power. The body diameter of this chuck is 4½" (the largest currently available in our chuck family). The chuck weighs approximately 8 lbs (fully assembled with the No. 2 Jaws). It is considerably heavier than the Talon Chuck (3.5 lbs) or Oneway Chuck (4.5 lbs) which makes it a very desirable chuck for large size lathe owners who want an exceptionally powerful grip for turning larger pieces. The Stronghold Chuck is operated by a key. Key operation provides two major advantages like one handed operation, solid holding power, and a 5 to 1 ratio assures powerful secure clamping. A wide range of accessory jaws are available for this chuck to cover all your turning requirements.
