The Sherline 1.3mm (.0512) 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 and causing the jaws to close and securely grip the part to be machined. This system is renowned for its accuracy, accommodating a narrow range of diameters with a tolerance of 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. Larger collets, known as "pot" chucks, are available for diameters up to 5/16″ and 8.0 mm, though they are not bored through and are only bored to a depth of .260″. This design may result in increased runout for parts extending further from the collet's front.

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. The 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.
