Sherline 7/32" (.2188") WW Collet
Ensures high centering accuracy
Fits into a tapered headstock adapter
Accommodates diameters up to 3/16"
Manufactured to WW specifications
Available in inch and metric sizes
The Sherline 7/32" (.2188") 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. This system provides exceptional accuracy, accommodating a small range of diameters with a tolerance of approximately ±.001″ (.02mm).
WW collets, distinct from milling collets, feature a hole that extends through both the collet and drawbar, 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 maximum runout is .002″ or less, and when the WW collet adapter is properly trued, it operates with optimal precision.
Sherline collets are manufactured to standard WW specifications and are available in inch sizes by 64ths of an inch from 1/64″ to 5/16″, as well as metric sizes from .3 mm to 8.0 mm by .1 mm increments. These collets are not hardened and have a shank diameter of .312-.313 with a .275-40 thread. It is important to verify compatibility with other manufacturers' WW collets to ensure they fit the Sherline adapter.
