Value Collection 230-4164 5C Round Steel Collet 1 Inch

Product Description

The VALUE COLLECTION 230-4164 is a 5C-style round steel collet designed for use in lathes, collet chucks, and other workholding equipment that accept the 5C collet standard. Built from steel, this collet holds round stock at a nominal 1-inch diameter with a total indicator runout (TIR) of 0.0005 inches, making it suitable for precision turning, milling, and grinding operations. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, both conforming to established 5C specifications. Machinists and toolroom technicians install this collet as a direct-fit workholding solution where consistent grip and minimal runout are required.

This collet is intended for use in any machine tool spindle or collet fixture that accepts the 5C collet form. Common applications include CNC and manual lathes, rotary indexers, collet blocks, and collet chucks used in production machining and job-shop environments. It is suited for holding 1-inch round bar stock, finished round parts, or tooling shanks during turning and secondary operations. Both production shops and toolroom environments rely on 5C collets for repeatable, quick-change workholding setups.

Key Features

• 5C collet standard with 1-inch nominal round bore capacity
• Steel construction for durability in production machining environments
• 0.0005-inch TIR for precision workholding with minimal runout

Compatibility

Designed as a standard 5C-style replacement or supplemental collet for use in machine tool spindles, collet chucks, collet blocks, and rotary indexers that accept the 5C collet form.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Before installing or removing the collet, ensure the machine spindle is fully powered down and at a complete stop. Inspect the collet bore and spindle taper for chips or debris before seating the collet, as contamination directly affects runout and workholding accuracy. Do not exceed the rated capacity of the collet or force oversized stock into the bore.
