Hertel 1-103-0600 6-jaw Lathe Chuck 6 Inch Plain Back

Product Description

The HERTEL 1-103-0600 is a self-centering 6-jaw manual lathe chuck designed for precision workholding on metal lathes. The 6-inch diameter body is machined from forged steel and mounts via a plain back interface, allowing adaptation to a wide range of lathe spindle nose configurations with an appropriate backplate. Six jaws provide uniform clamping force distribution around the workpiece, reducing distortion on thin-walled or delicate parts. The chuck handles stock from 5/16 inch minimum jaw capacity up to 6-19/64 inches maximum jaw capacity and is rated to 2,500 RPM. A 1.6535-inch through-hole diameter accommodates bar stock fed through the spindle. Machinists and toolroom technicians working in production or job-shop environments are the primary installers.

This chuck is suited for general turning operations on manual engine lathes in both job-shop and light production settings. The plain back mount design gives the operator flexibility to machine a custom backplate to match the specific lathe spindle nose — a common requirement when fitting aftermarket chucks to older or non-standard machines. The adjustable jaw feature allows fine-tuning of concentricity, making this chuck appropriate for applications where runout control is critical, such as finishing passes on precision-diameter shafts or thin-walled cylindrical parts.

Key Features

• 6-jaw self-centering design distributes clamping load evenly, reducing workpiece distortion on thin-walled stock
• Forged steel body construction for rigidity and durability under continuous cutting loads
• Adjustable jaws for fine concentricity correction after initial setup
• Plain back mount for compatibility with custom-machined backplates across a wide range of lathe spindle nose styles
• 1.6535-inch through-hole diameter supports bar-feed operations
• 2,500 RPM maximum speed rating suitable for standard turning applications

Compatibility

Designed as a plain back mount lathe chuck requiring a separately sourced or shop-machined backplate matched to the specific lathe spindle nose. No specific machine model compatibility is stated by the manufacturer for this part.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with lathe spindle nose configurations and backplate machining procedures. Power down and lock out the lathe at the main disconnect before removing or installing any chuck. The plain back mount requires a precisely fitted backplate — verify runout with a dial indicator after mounting before taking any cuts. Follow the lathe manufacturer's torque and mounting guidelines for backplate-to-spindle attachment hardware.
