Value Collection 230-6003 3 Inch 3 Jaw Lathe Chuck 5C

Product Description

The VALUE COLLECTION 230-6003 is a 3-inch diameter, 3-jaw self-centering manual lathe chuck designed for precision workholding on lathes equipped with a 5C shank spindle mount. The body is cast from cast iron for rigidity and durability under continuous machine shop use. The self-centering jaw design allows all three jaws to move simultaneously, reducing setup time when gripping round or hexagonal stock. A through-hole diameter of 0.765 inches accommodates bar stock fed through the spindle. TIR repeatability is rated at 0.003 inches, making it suitable for production and tool room applications where consistent runout control matters. Licensed machinists and machine shop technicians are the primary installers and operators.

This chuck is suited for manual lathe operations in job shops, tool rooms, and production environments. The 5C shank mount is a widely used spindle interface found on collet-ready lathes and indexing fixtures. The package includes a set of external jaws and a set of internal jaws, giving the operator flexibility for both OD and ID gripping applications. One-piece, non-reversible jaw construction keeps the setup straightforward and eliminates loose jaw segments during changeovers.
