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.

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.

More flexible than indexing collet fixtures for workholding—these fixtures hold a wide range of part sizes without swapping out collets. Also known as spindexers, they’re often used to drill hole patterns, shape punches, and sharpen cutting tools. With three jaws that move together, the chuck auto-centers parts and even grips workpieces that are out-of-round or have rough surfaces. Ground to tight tolerances, the base sits flat when mounted to machine tables in either a horizontal or vertical position, preventing misalignment. With a hole through their center, they have no trouble holding long parts too. The chuck comes off, so you can also use them as rotary tables.
