Lathe Chucks for Non-Round Workpieces
Adjust each jaw on these chucks separately to hold rectangular or odd-shaped workpieces. Also known as independent chucks, they have four jaws that each have their own adjustment screw. For quicker setups, you can also remove two jaws and clamp with the remaining two. All jaws are reversible, so you can install them for either an inside or an outside grip. Use the included wrench to move them in or out. 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. They last longer than cast iron chucks, and you can run them at higher speeds.
Use high-pressure grease to improve grip and prolong the life of your chuck.
You’ll need a mounting plate to attach the chuck to your lathe. Choose a mounting plate that matches the diameter of the lathe chuck, your lathe’s spindle type, and the spindle OD.

Stationary Jaw Clamping Fixtures
Mount these fixtures to a milling machine, drill press, or other flat surface and use the jaws to grip workpieces. Their low-profile design maximizes tool clearance, which helps you machine efficiently. The jaws are precision ground to tight tolerances for repeatable centering that’s accurate within 0.02 mm. These fixtures are self-centering—they use scroll actuation, which means that all jaws move in unison to center the workpiece as they close.
Each fixture comes with reversible jaws, which you can install for either an inside or outside grip. Use the included wrench to open or close the jaws.
Fixtures with four jaws have more holding power than those with three jaws, so they’re often used on square or rectangular workpieces.
