Value Collection 429-3108 10 in 3-jaw Lathe Chuck D1-8

Product Description

The VALUE COLLECTION 429-3108 is a manual, self-centering 3-jaw lathe chuck designed for use on engine lathes and manual turning centers. It measures 10 inches in diameter and mounts via a D1-8 direct camlock spindle connection. The chuck body is cast iron, providing rigidity and vibration damping during turning operations. Jaws are two-piece and reversible, allowing the chuck to grip both outside and inside diameters without a jaw swap. The through-hole diameter is 2.7559 inches (70 mm), accommodating bar stock fed through the spindle. This chuck is installed by machinists and toolroom technicians in job shop and production turning environments.

The 429-3108 is suited for manual lathes with a D1-8 camlock spindle nose in both job shop and light production settings. The self-centering scroll mechanism allows fast, repeatable workpiece setup for round and hex stock. The reversible two-piece jaw set extends the range of workpiece diameters the chuck can hold without requiring additional jaw sets. Typical applications include turning, facing, and boring operations on ferrous and non-ferrous materials in a machine shop environment.

Installation Notes

Installation should be performed by a qualified machinist with the lathe powered off, spindle locked, and the machine isolated from its power source. The D1-8 camlock studs should be inspected and cleaned before mounting; engage all camlock pins evenly and verify secure seating before operation. Always confirm runout with a dial indicator after mounting before taking the first cut. Jaw removal and reversal should be performed with the chuck off the spindle on a clean, stable work surface.
