Returns Simplified.The Sherline 6.1mm (.2402) 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.
WW collets are distinct from milling collets due to their through-hole design, allowing stock to pass entirely through. However, the maximum diameter for stock passing through is 3/16″ or 4.5mm. Collets larger than this diameter, known as “pot” chucks, are not bored through and are only bored to a depth of .260″. This design may result in increased runout further from the collet’s front, depending on the setup and part length.
Sherline collets are manufactured to standard WW specifications, with a shank diameter of .312-.313 and a .275-40 thread. They are not hardened and are available in both inch and metric sizes, with metric collets beginning with part number 1178. It is crucial to verify compatibility with Sherline’s adapter when using WW collets from other manufacturers, as some may not fit. Sherline also offers a slightly larger adapter and drawbar set to accommodate certain other brands of 8 mm collets.
