ER Collet-to-Sherline Chuck Arbor
When using a large mill or lathe with 5C, ER or other large collets it is sometimes helpful to have a way to change to a small chuck quickly. These adapters have either a 1/2″ shank (10660) or a 5/8″ shank (10650). On the other end is a 3/4-16 thread that accepts any Sherline 2.5″ or 3.1″ chuck. This allows you, without changing your spindle or going to another machine, to quickly install a Sherline 3- or 4-jaw chuck. Just insert the shank of the adapter attached into a 1/2″ or 5/8″ collet. Now you can chuck up parts that could not be easily held in a collet. T.I.R. of the adapter is specified to be 0.0005″ (0.013mm) or less. The unhardened steel adapters have a black oxide finish to prevent rust.

Soft steel jaws (unhardened and unmachined) are also available when building your own chuck.
2.5″ 3-Jaw Chucks – Various Thread
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.
