5C Collet to Lathe Chuck Adapters

No need to break down a collet set up when a workpiece doesn't fit a 5C collet. Install one of these lathe chuck adapters in your 5C collet chuck or holder and its three jaws will securely grasp the workpiece. These chuck adapters are self centering—all three jaws move in unison, centering the workpiece as they close. Use the included lathe chuck wrench to open and close the jaws.

Lathe Chucks

Mount these chucks to a lathe's spindle to hold round workpieces. Also known as scroll chucks, they are self centering—all jaws move in unison, centering the workpiece as they close. Made of forged steel, these chucks are strong and wear resistant, so they maintain their shape even with continuous use. They’re often used for precision machining. You can run them at higher speeds than cast iron chucks, and they’ll last longer. Use the included lathe chuck wrench to open and close the jaws.

Fixed One-Piece Keyed Jaw Chucks

Chucks with fixed jaws come with one set of outside jaws and one set of inside jaws. These jaws are one-piece and keyed, so they’re best for rigid and permanent setups where you don’t need to change your jaw style. They’re commonly used in dedicated turning operations or roughing applications.

Economy Lathe Chucks

Choose these lathe chucks when high precision isn’t critical. Made of cast iron, they don't match up to the same tight tolerances as forged steel lathe chucks. This means they are only rated to half the maximum speed, so they may wobble at high speeds. Also known as scroll chucks, they are self-centering—all three jaws move together, centering the workpiece as they close. Use the included lathe chuck wrench to open and close the jaws. You’ll need a mounting plate (not included) to connect these chucks to your lathe.
