Value Collection 1230-4245 5C Round Collet 24mm

Product Description

The VALUE COLLECTION 1230-4245 is a 5C round collet machined from steel, designed to grip round workpieces in lathes, milling machines, and other spindle-driven equipment that accept the 5C collet system. With a collet size of 24.00 mm and a total indicator runout (TIR) of 0.015 mm, this collet delivers the concentricity required for precision turning and light milling operations. The internal thread size is 1.041 inches-24 and the external thread size is 1.242 inches-20, conforming to standard 5C system dimensions. Machinists and tool room technicians install this collet as a direct workholding component.

This 5C round collet is suited for production turning and general-purpose machining environments where consistent grip on round bar stock or round-shank tooling is required. It fits standard 5C-compatible spindles found on bench lathes, turret lathes, and collet fixtures used in both job shop and production machine shop settings. The steel construction holds up to repeated use in normal cutting operations.

Installation Notes

Installation is performed by a machinist or tool room technician. Before inserting or removing the collet, power down the machine and ensure the spindle has come to a full stop. Threads should be inspected for damage and kept clean and lightly lubricated per the machine manufacturer's guidance. Do not force a collet into a damaged or incompatible spindle nose.
