Hertel 1-202-0500 3-jaw Lathe Chuck 5 Inches

Product Description

The HERTEL 1-202-0500 is a self-centering 3-jaw manual lathe chuck with a 5-inch diameter and plain back mount, designed for general-purpose turning operations on metal lathes. The cast iron body delivers rigid workholding with solid, non-reversible jaws that provide consistent grip across a wide jaw capacity range from 1/8 inch minimum to 4-59/64 inch maximum. With a maximum spindle speed of 3,200 RPM and tight runout tolerances, this chuck suits production and toolroom environments where repeatability and concentricity matter. Installed by machinists and tool-and-die professionals, the chuck weighs 11.5 pounds and is built for sustained shop use.

This chuck is suited for manual lathe applications in machine shops, maintenance facilities, and production environments. The self-centering scroll mechanism allows fast workpiece changes without individual jaw adjustment, making it practical for repetitive turning, facing, and boring operations on round or hex stock. The plain back mount configuration requires a lathe-specific backplate or adapter matched to the spindle nose of the host machine. Verify spindle nose type and backplate compatibility before installation.

Compatibility

Designed as a plain back mount lathe chuck requiring a separately sourced backplate or adapter matched to the host lathe spindle nose. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist familiar with lathe spindle configurations. Disengage and lock out the lathe before mounting or removing the chuck. A properly fitted backplate matched to the spindle nose thread or taper is required for a secure mount. Verify runout after installation using a dial indicator before taking cuts.
