The Sherline Precision 3-Jaw Chuck WW Collet (Metric 3.2 mm) is a highly accurate tool designed for mounting cylindrical parts or bar stock in a lathe. This collet is a small, precision 3-jaw chuck that fits into a special tapered adapter in the headstock. A drawbar, which passes through the headstock and threads into the backside of the collet, is used to draw the collet up into the tapered adapter. This action causes the jaws of the collet to close down, gripping the part to be machined with a high degree of centering accuracy.
The Sherline WW Collets are unique in that they have a hole through the collet and drawbar. This allows for the passage of a maximum diameter stock of 3/16″ or 4.5mm.
