The Sherline .8mm (.0315) 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 through the headstock 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 through-hole design, allowing stock to pass entirely through up to a maximum diameter of 3/16" or 4.5mm. Collets larger than this diameter are known as "pot" chucks and are not bored through, being only .260" deep. The collet's maximum runout is .002" or less, ensuring high precision when the WW collet adapter is properly trued.

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 important to verify compatibility with other manufacturers' WW collets to ensure they fit the Sherline adapter. Metric sizes range from .3 mm to 8.0 mm in 0.1 mm increments, with special sizes available upon request.
