Sherline 3-jaw chucks are designed with synchronized jaws that move together to automatically center round or hex stock to within a few thousandths of an inch. They offer the fastest and most convenient way to hold work in a lathe, making them one of Sherline’s most popular accessories.

These chucks can grip externally on bar stock or internally on tubing. The jaws are reversible to handle a wider range of part sizes.

Compatibility with Sherline and Other Lathes
Chucks are available with different spindle threads for use on Sherline lathes (3/4-16) and other machines such as older Unimat models (12mm x 1mm or 14mm x 1mm) or Sears 6" lathes (1/2-20).
Note: Thread sizes other than 3/4″ x 16 are custom made and require 5–7 business days.

Jaw Options

• If you prefer jaws with a looser fit for faster operation (where maximum accuracy isn’t critical), add a note requesting “loose jaws” below.

• Soft steel jaws (unhardened and unmachined) are also available when building your own chuck.
