Value Collection 530-4226 5C Square Collet 13/32 Inch

Product Description

The VALUE COLLECTION 530-4226 is a 5C square collet machined from steel for use in 5C collet chucks, collet closers, and indexing fixtures found on lathes and collet-specific workholding setups. It accepts 13/32 inch square stock and holds a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision turning and machining operations where concentricity matters. The internal thread measures 1.041 inch-24 and the external thread measures 1.242 inch-20, conforming to the standard 5C interface. Machinists and tool room technicians install this collet when working with square-profile bar stock or square-ground workpieces.

This collet is intended for use in machine shop environments where 5C-compatible workholding equipment is in service. It fits the standard 5C spindle interface used widely in production lathes, rotary tables, and manual collet fixtures. The square bore geometry makes it the correct selection when round-bore collets are not appropriate for the workpiece profile. Applications include light turning, facing, and secondary operations on square stock in both job shop and production settings.

Key Features

• 13/32 inch square bore for square-profile workpiece clamping
• 0.0005 inch TIR for consistent concentricity during machining
• 1.041 inch-24 internal thread matches standard 5C collet closer interface
• 1.242 inch-20 external thread for standard 5C chuck engagement
• Steel construction for durability under repeated clamping cycles

Compatibility

Designed as a direct-fit replacement or spare for standard 5C collet systems. Specific machine compatibility depends on the collet chuck or closer in use; verify that your spindle or fixture accepts the standard 5C external thread specification before installation.

Installation Notes

Installation is performed by a machinist or toolroom technician. Power down and de-energize the machine spindle completely before inserting or removing any collet. Inspect the collet bore and the spindle seat for chips or burrs that could affect seating and runout. Do not exceed the rated clamping capacity of the collet closer or chuck when tightening.
