WW Collet-to-Thread Chuck Adapter

The WW to 3/8-24 thread collet adapter is the same as the 8.0 mm to 3/8 x 24 thread adapter (P/N 2092), but with a smaller barrel diameter, so it will work with our Sherline lathe. The barrel diameter is .3120″-.3125″ and is designed to be used with our WW Collet Adapter (P/N 11580).

NOTE: We also offer other collet-to-thread chuck adapters to mount our 3- and 4-jaw chucks on non-Sherline lathes typically used by watchmakers or jewelers. CLICK HERE to view the options.
