Value Collection 429-66001 6-jaw Lathe Chuck 6-19/64 in

Product Description

The VALUE COLLECTION 429-66001 is a 6-jaw self-centering manual lathe chuck designed for precision workholding on manual lathes. With a chuck diameter of 6-19/64 inches (159.94 mm) and a through-hole diameter of 1.535 inches, it accommodates a range of workpiece sizes common in machine shop environments. The cast iron body provides rigidity and resistance to deformation under clamping loads. Six jaws distribute clamping force evenly around the workpiece, reducing distortion on thin-walled or delicate parts. A TIR repeatability of 0.013 mm supports consistent part positioning across repeated setups. This chuck is installed and serviced by machinists and toolroom technicians.

The 429-66001 is suited for use on manual engine lathes in production and toolroom settings where accurate, repeatable workholding is required. The self-centering action allows faster part loading compared to independent-jaw chucks, making it practical for moderate-volume runs. The plain back mount type requires a backing plate matched to the lathe spindle nose. Two-piece, reversible jaws extend the usable gripping range, allowing the chuck to hold both smaller-diameter and larger-diameter stock without a separate jaw set.

Key Features

• 6-jaw design distributes clamping load evenly, reducing deflection on thin-walled or precision workpieces
• Self-centering mechanism speeds up part loading and reduces setup time versus independent-jaw configurations
• TIR repeatability of 0.013 mm supports consistent part positioning across setups
• Reversible two-piece jaws provide both internal and external gripping without a separate jaw set
• Plain back mount accommodates a wide range of lathe spindle nose configurations via a matched adapter plate
• Cast iron body construction delivers rigidity under clamping loads

Compatibility

Designed as an OEM-style manual lathe chuck replacement or addition for lathes accepting a plain back mount with a compatible adapter plate. Specific lathe model compatibility depends on the spindle nose configuration and adapter plate selected by the installer.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power off and lock out the lathe before mounting or removing the chuck. A plain back adapter plate matched to the lathe spindle nose is required and must be faced true before mounting the chuck. Verify runout with a dial indicator after installation before returning the machine to service.
