10" 3-Jaw Self-Centering Lathe Chuck #424499-7A, Square Adapter Plate, Approx. 4" Bore

A large 3-jaw self-centering manual lathe chuck mounted on a square steel adapter plate, offered here as a complete assembly. The chuck body measures approximately 10 inches in diameter with a through-bore of approximately 4 inches, and three serrated jaws arranged in a standard scroll configuration for self-centering workpiece clamping. The square adapter plate, visible in multiple photos, is approximately 10 inches by 10 inches and features a pattern of bolt holes and counterbored mounting holes for machine installation. A reference number stamped into the plate reads 424499-7A; no manufacturer name or brand logo is legibly visible on any surface. The assembly is heavy-duty cast iron construction consistent with large-bore engine lathe or vertical turret lathe applications requiring substantial workholding capacity. The jaws appear to be in the standard two-piece reversible configuration. The chuck scroll body and jaw slides show typical service wear consistent with industrial use. Mounting interface of the adapter plate back face is not confirmed from available photos; buyers should verify spindle nose compatibility prior to installation. This type of large chuck and plate assembly is commonly found on floor-standing engine lathes, vertical lathes, and heavy-duty turning centers used in industrial metalworking and fabrication operations.
