Value Collection 230-4426 5C Expanding Collet Steel

Product Description

The VALUE COLLECTION 230-4426 is a 5C expanding collet manufactured from steel, designed for use in lathe and workholding applications where secure, accurate gripping of workpieces is required. This collet features a 2-inch head diameter and a 1.5-inch head length, with a concentricity rating of 0.0020 inches TIR for consistent, repeatable runout performance. It accepts a grip range from 0.75 inches up to 1.9375 inches, making it suitable for a broad range of round and workpiece diameters. Machinists and toolroom technicians install this collet in 5C-compatible spindles and fixtures on manual or CNC lathes.

This expanding collet is intended for precision workholding in machine shop environments, including production turning, grinding, and secondary operations. The expanding design grips from the inside of a bore or recess, allowing secure holding of tubular or pre-bored workpieces. It is appropriate for both job-shop and production-floor use where 5C spindle compatibility is standard.

Key Features

• 2-inch head diameter with 1.5-inch head length fits standard 5C spindle noses

Compatibility

Designed as an OEM-style replacement or direct fitment for standard 5C collet-ready lathes, grinding machines, and workholding fixtures that accept 5C expanding collets.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with 5C collet systems. Power down and de-energize the spindle drive fully before inserting or removing the collet. Ensure the spindle bore and collet taper are clean and free of chips or debris before seating. Do not force the collet into the spindle; hand-thread the draw tube to proper engagement before applying closing force.
