Value Collection 1230-4234 5C Round Collet 18.50mm

Product Description

The VALUE COLLECTION 1230-4234 is a 5C round collet machined from steel, designed to hold round workpieces in 5C-compatible spindles, chucks, and collet closers. With a collet size of 18.50mm and a total indicator reading (TIR) of 0.015mm, this collet provides repeatable, accurate workholding for turning, grinding, and secondary machining operations. 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. It weighs 0.5 pounds. Machinists and toolroom technicians install this collet as part of standard 5C workholding setups on lathes and grinders.

This collet is suited for machine shops running 5C spindle equipment in production or jobbing environments. The round profile accepts cylindrical bar stock and turned workpieces. It is a direct-fit component for any machine tool or fixture designed around the 5C collet standard, which is widely used in both manual and CNC lathe applications requiring consistent part location and grip.

Compatibility

Designed as an OEM-style replacement or standard addition for machine tools and fixtures built to the 5C collet standard.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with 5C workholding systems. Power down and de-energize the machine spindle completely before inserting or removing any collet. Inspect the collet bore and the spindle taper for burrs or debris before seating the collet, as contamination will affect TIR. Do not exceed the rated collet capacity, as overloading the bore can damage the collet and the spindle nose.
