Value Collection 230-6004 4 in 3 Jaw Lathe Chuck 5C

Product Description

The VALUE COLLECTION 230-6004 is a self-centering, three-jaw manual lathe chuck designed for precision workholding on lathes equipped with a 5C spindle mount. Built from cast iron, this chuck measures 4 inches in diameter and features a 0.765-inch through-hole, allowing bar stock to feed through the spindle. The self-centering scroll mechanism closes all three jaws simultaneously, reducing setup time compared to independent-jaw chucks. It ships with both a set of external jaws and a set of internal jaws, giving the operator flexibility to grip a range of workpiece profiles without purchasing additional accessories. TIR repeatability is rated at 0.0030 inches, suitable for general turning and light production work.

This chuck is intended for manual lathe applications in machine shops, toolrooms, and maintenance facilities. It mounts directly to lathes with a 5C collet-style spindle interface, a common configuration on smaller engine lathes and toolroom lathes. The one-piece jaw design and non-reversible jaw configuration make it straightforward to set up for standard OD gripping tasks. Both the included external and internal jaw sets expand its usefulness across different part geometries without requiring a separate chuck body.

Installation Notes

Installation should be performed by a qualified machinist or machine tool technician. Power down and lock out the lathe fully before mounting or removing the chuck. Verify spindle thread or collet-nose interface matches the 5C shank specification before attempting to seat the chuck. Confirm jaw seating and chuck runout with a dial indicator before commencing any cutting operation.
