The Sherline 6.2mm (.2441) WW Collet offers a precise and efficient method for mounting cylindrical parts or bar stock in a lathe, ensuring high centering accuracy. This collet functions as a small, precision 3-jaw chuck that fits into a specially designed tapered adapter within the headstock. The drawbar, threading through the headstock and into the collet's backside, pulls the collet into the adapter, causing the jaws to close and securely grip the part for machining. Each collet size accommodates a limited range of diameters, approximately ±.001″ (.02mm).

WW collets are distinct from milling collets due to their through-hole design, allowing stock with a maximum diameter of 3/16″ or 4.5mm to pass entirely through. Collets larger than this diameter are known as "pot" chucks and are not bored through, being only .260″ deep. The collet's maximum runout is .002″ or less, and when the WW collet adapter is properly trued, it operates with optimal accuracy.

Sherline collets are logically numbered, with inch collets starting with part number 1160 and metric collets with 1178, followed by digits indicating size. These collets are not hardened but are manufactured to standard WW specifications. It is crucial to verify compatibility with other manufacturers' WW collets, as Sherline collets have specific shank diameters and thread specifications. Special sizes and larger "pot" chucks are available upon request.
