The Sherline 2.3mm (.0906) 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. A drawbar threads into the collet's backside, drawing it into the adapter, which causes the jaws to close and securely grip the part to be machined. The collet system is known for its accuracy, accommodating a small 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 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, only to a depth of .260″. The collet's maximum runout is .002″ or less, and when the WW collet adapter is properly trued, it ensures optimal performance.

Sherline collets are manufactured to standard WW specifications and are not hardened. They feature 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. Sherline also offers a slightly larger adapter and drawbar set to accommodate some other brands of 8 mm collets.
