Value Collection 230-4130 5C Round Steel Collet 15/32 in

Product Description

The VALUE COLLECTION 230-4130 is a 5C-style round collet machined from steel for use in lathes, collet chucks, and other 5C-compatible workholding systems. It accepts round stock at a 15/32 inch bore size and holds total indicated runout (TIR) to 0.0005 inches, making it suitable for precision turning, grinding, and milling operations. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C specifications. Machinists and toolroom technicians install this collet as part of a workholding setup on manual or CNC lathes.

This collet is suited for machine shop environments where consistent, repeatable clamping of round bar stock or cylindrical workpieces is required. The 15/32 inch capacity makes it appropriate for holding standard fractional-inch round stock in production turning and precision finishing operations. It fits standard 5C collet closers, spindle-nose chucks, and collet blocks used across a wide range of manual and CNC turning equipment.

Key Features

• 15/32 inch bore capacity for round workpieces
• 0.0005 inch TIR for precision concentricity
• 1.041-24 internal thread per 5C standard
• 1.242-20 external thread per 5C standard
• Steel construction for durability in production environments

Compatibility

Designed as a standard 5C-style replacement or addition for use with 5C collet closers, collet chucks, and collet blocks in round-collet workholding applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing collets. Ensure mating threads and the collet seat are clean and free of chips or debris before seating the collet. Do not exceed the rated bore capacity, as over-range clamping can damage the collet and reduce accuracy.
