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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e6-jaw design distributes clamping load evenly, reducing deflection on thin-walled or precision workpieces\u003c\/li\u003e\n  \u003cli\u003eSelf-centering mechanism speeds up part loading and reduces setup time versus independent-jaw configurations\u003c\/li\u003e\n  \u003cli\u003eTIR repeatability of 0.013 mm supports consistent part positioning across setups\u003c\/li\u003e\n  \u003cli\u003eReversible two-piece jaws provide both internal and external gripping without a separate jaw set\u003c\/li\u003e\n  \u003cli\u003ePlain back mount accommodates a wide range of lathe spindle nose configurations via a matched adapter plate\u003c\/li\u003e\n  \u003cli\u003eCast iron body construction delivers rigidity under clamping loads\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style manual lathe chuck replacement or addition for lathes accepting a plain back mount with a compatible adapter plate.
