The Sherline 1.1mm (.0433) 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's backside, drawing it into the adapter, which causes the jaws to close and securely grip the part for machining.

WW collets are distinct from milling collets due to their design, which includes a hole running through both the collet and drawbar. This feature allows stock with a maximum diameter of 3/16″ or 4.5mm to pass entirely through the collet. Collets larger than this diameter are known as "pot" chucks and are not bored through, being only .260″ deep. The collet's accuracy is notable, with a maximum runout of .002″ or less, provided the WW collet adapter is trued as per instructions.

Sherline collets are logically numbered, with metric collets beginning with part number 1178 followed by two digits indicating the size in 0.1 mm increments. These collets are manufactured to standard WW specifications, with a shank diameter of .312-.313 and a .275-40 thread. It is crucial to verify compatibility with other manufacturers' WW collets to ensure they fit the Sherline adapter.
