Description
Sherline 1030 – 3.1 in 4-Jaw Chuck
This larger chuck takes up no more center-to-center space than the 2.5″ chuck, but it will hold larger work. It has a clamping range of from 3/32″ (2 mm) up to 1-1/2″ (38 mm) diameter with the jaws in the normal position. With the jaws in the reversed position, work up to 2-3/4″ (70 mm) can be gripped. The hole through the chuck is .687″ (17 mm). A hex key (provided) is used to tighten each jaw individually. A groove is machined around the base of the chuck so that angle clamps can be used to mount it to the table of a mill as a holding fixture. The chuck has a 3/4-16 thread to fit Sherline’s spindle and other machines using that thread.
