Value Collection 230-4115 5C Steel Collet 15/64 in

Product Description

The VALUE COLLECTION 230-4115 is a 5C-style round collet machined from steel for use in 5C-compatible spindles and collet chucks on lathes, milling machines, and grinding equipment. It holds round workpieces at a nominal bore size of 15/64 inches with a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision turning and grinding operations where concentricity matters. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C collet geometry. Machinists and toolroom technicians are the primary installers of this collet type.

This collet is designed for round stock and is used in job shops, toolrooms, and production environments wherever a 5C spindle nose is present. Typical applications include holding bar stock for turning operations on manual or CNC lathes, as well as secondary operations on milling machines equipped with 5C indexing fixtures. The 15/64-inch bore size accommodates workpieces at that specific diameter and is not intended for square or hex stock profiles.

Key Features

• 15/64-inch round bore for precise workholding of round stock
• 0.0005-inch TIR for high concentricity in turning and grinding applications
• Steel construction for durability under repeated clamping cycles
• 1.041 inches-24 internal thread conforms to standard 5C collet specification
• 1.242 inches-20 external thread for compatibility with standard 5C closers and chucks

Compatibility

Designed as a standard 5C-style replacement or supplemental collet for use in any machine spindle or fixture built to the 5C collet standard with a round-bore configuration.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing any collet. Inspect the collet bore and spindle taper for chips or burrs before seating, as debris will affect runout. Do not exceed the rated bore size when clamping workpieces, as overloading a collet can damage both the collet and the spindle nose.
