The Sherline 1.9mm (.0748) 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 in turn closes the jaws to securely grip the part being machined.

WW collets are distinct from milling collets due to their design, which includes a hole running entirely through both the collet and drawbar. This feature allows stock with a maximum diameter of 3/16″ or 4.5mm to pass completely through the collet. The collet's accuracy is notable, with a maximum runout of .002″ or less, provided the WW collet adapter is trued as per instructions, ensuring optimal performance.

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, although they are not hardened. It is crucial to verify compatibility with other manufacturers' WW collets to ensure they fit the Sherline adapter.
