Value Collection 230-4225 5C Round Collet 25mm

Product Description

The VALUE COLLECTION 230-4225 is a 5C round collet machined from steel for use in 5C-compatible lathes, collet chucks, and indexing fixtures. It accepts workpieces with a 25mm collet size and holds a TIR of 0.015mm, providing consistent, repeatable workholding accuracy for turned and cylindrical parts. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, matching standard 5C collet closer specifications. Machinists and tool room technicians rely on this collet for production turning, second-operation work, and manual lathe setups where quick part changeover and accurate concentricity are required.

This collet is suited for machine shops running 5C-compatible spindles in both manual and CNC lathe applications. It is a standard round collet, appropriate for gripping round-section bar stock, turned blanks, and cylindrical workpieces. Typical install environments include job shops, production turning cells, and tool rooms requiring reliable steel collets that meet standard 5C dimensional specifications. The steel construction provides durability under repeated clamping cycles and normal cutting loads.

Key Features

• 25mm collet size for gripping round cylindrical workpieces
• TIR of 0.015mm for consistent concentricity and repeatable part location
• Steel construction for durability through repeated clamping cycles
• Internal thread size of 1.041 inches-24 matches standard 5C closer threads
• External thread size of 1.242 inches-20 for standard 5C spindle nose engagement
• Round collet style compatible with standard 5C collet chucks and draw-type closers

Compatibility

Designed as an OEM-style replacement or standard-service collet for machine tool setups using 5C-compatible spindles, collet chucks, and collet closers that accept the standard 5C thread and taper interface.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Power down and lock out the lathe or machine tool spindle completely before inserting or removing the collet. Inspect collet bore and seating taper for chips, burrs, or wear before installation, as contamination will degrade TIR performance. Do not exceed the recommended workpiece diameter range for a 5C round collet, and torque the collet closer only to the machine manufacturer's specified setting.
