Sherline Rotary Table Collet Adapters 1164

Sherline Rotary Table Collet Adapters 1164

The collet fixture was designed to be mounted either on the surface of the rotary table or on the mill table. A knurled ring allows WW collets to be tightened without the use of a drawbolt from the back. This is particularly useful for clockmakers for heartcutting on a gear blank that has a pinion shaft attached that can be held in a collet. A bushing is provided that fits into the center hole of the rotary table and helps locate the fixture on center. T-nuts and attaching screws are also provided for clamping the fixture in place in the rotary table or mill table T-slots.

WW collets vary somewhat in size depending on manufacturer. The 1164 adapter holds collets made by Sherline and others with a .312-.313″ body size and .275-40 thread, which we refer to as WW collets. Other common “WW” collets have a body size of .314-.315, which we refer to as “8.0 mm” collets. A fixture for these collets is also available as P/N 1165. It looks identical except that it is identified by a groove machined around the body. If you are using a brand of collets other than Sherline, measure the body diameter with a micrometer before deciding which collet fixture to order.
