They are used to hold round, square or rectangular work. Since the jaws adjust independently, it is possible to achieve perfect centering of the part with proper adjustment. This process is more time consuming than using a 3-jaw chuck, but it offers the most accuracy. Sherline's 3.1" 4-jaw independent chuck is now available with a 22 x 1.5 mm thread for use on ER-16 spindles. NOTE The chuck should not be used in applications where spindle speed exceeds 3000 RPM. If purchasing any of these chucks for use on a non-Sherline ER-16 spindle, confirm that the spindle nose thread is 22 x 1.5 mm before purchasing. The Sherline chuck has a collar that is machined flat at the back to seat against the face of the Sherline ER-16 spindle. This may not be compatible with some non-Sherline ER-16 collet adapters or industrial tool holders. Runout accuracy cannot be guaranteed unless used with a Sherline spindle.
