The Sherline 4.0mm (.1575) 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 mechanism involves a drawbar threading through the headstock and into the collet, which, when tightened, draws the collet into the adapter, causing the jaws to close and securely grip the part to be machined.
WW collets are distinct from milling collets due to their through-hole design, allowing stock to pass entirely through. The maximum diameter stock that can pass through is 3/16" or 4.5mm. Collets larger than this diameter are referred to as "pot" chucks and are not bored through, being only .260" deep. 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 it is crucial to verify compatibility with other manufacturers' WW collets to ensure they fit the Sherline adapter. The collets are available in both inch and metric sizes, with the metric series beginning with part number 1178, followed by digits indicating size in 0.1 mm increments. Special sizes can be ordered if needed.
