The Sherline 5/64" (.0781) WW Collet offers a precise and efficient solution for mounting cylindrical parts or bar stock in a lathe. 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, pulling it into the adapter and causing the jaws to close and securely grip the workpiece.

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. Collets larger than this diameter are known as "pot" chucks and are not bored through, being only .260" deep. The collet's accuracy is notable, with a maximum runout of .002" or less, ensuring high precision when the WW collet adapter is properly trued.

Sherline collets are logically numbered, with inch collets starting with part number 1160 followed by size in 64ths of an inch. 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. Sherline also offers a slightly larger adapter and drawbar set to accommodate some other brands of 8 mm collets.
