Jet 321519 Collet Closer W Series Lathes

Product Description

The JET 321519 is a collet closer designed for use with JET W Series lathes. A collet closer mounts to the lathe spindle and provides a fast, repeatable clamping mechanism for round stock, bar stock, and collet-held workpieces. It replaces the need to manually tighten a chuck for production-style turning operations, reducing setup time between passes. Machinists and tool room technicians install this component when consistent workholding concentricity is required across repeated cuts. At 22 pounds, the 321519 is a substantial assembly suited for professional shop use.

This collet closer is intended for use on JET W Series lathe models. It is a direct-fit accessory for those machines, enabling collet-based workholding without modification to the lathe headstock. Typical applications include production turning, shaft work, and any operation where a collet provides better grip and runout control than a standard three-jaw chuck. Installation is performed by a machinist or qualified lathe operator familiar with JET W Series equipment.
