Value Collection 230-4102 5C Round Steel Collet 1/32 in

Product Description

The VALUE COLLECTION 230-4102 is a 5C round steel collet sized at 1/32 inch, designed for use in 5C-compatible collet chucks on lathes, milling machines, and grinding equipment. The collet achieves a total indicator reading (TIR) of 0.0005 inches, delivering the concentricity precision required for close-tolerance turning and cylindrical grinding work. The internal thread measures 1.041 inches at 24 threads per inch, and the external thread measures 1.242 inches at 20 threads per inch. Machinists and toolroom technicians install this collet when holding small-diameter round stock or finished parts that require minimal runout during machining operations.

This 5C collet is suited for manual and CNC lathes, rotary indexers, spin fixtures, and collet blocks equipped with the 5C standard. It is a common fit in job shops, toolrooms, and production environments where 1/32 inch round stock or similarly sized workpieces are machined to tight dimensional tolerances. The steel construction handles typical cutting forces encountered in turning and light milling without deforming the collet bore over repeated use cycles.

Key Features

• 1/32 inch bore sized for round workpieces and stock
• 0.0005 inch TIR for high-concentricity workholding
• 1.041 in-24 internal thread compatible with standard 5C spindle noses
• 1.242 in-20 external thread for collet closer engagement
• Steel construction for durability under repeated clamping cycles
• 5C standard form factor fits a wide range of 5C-compatible chucks and fixtures

Compatibility

Designed as an OEM-style replacement or standard-stock collet for machinery equipped with 5C collet spindles and closers accepting the 1.041 in-24 internal and 1.242 in-20 external thread specifications.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before installing or removing a 5C collet, disengage the collet closer and ensure the spindle is fully stopped and the machine is powered down or in an e-stop state. Inspect the collet bore and spindle taper for chips or debris before seating the collet, as contamination directly affects TIR. Do not overtighten the collet closer beyond the workpiece clamping requirement, as excessive force can distort the collet bore and degrade concentricity.
