Value Collection 230-4105 5C Steel Round Collet 5/64

Product Description

The VALUE COLLECTION 230-4105 is a 5C round collet machined from steel, designed to hold workpieces during turning, grinding, and milling operations on lathes and other spindle equipment that accept the 5C collet standard. The collet measures 5/64 inch in bore diameter and delivers a total indicator runout (TIR) of 0.0005 inches, providing the close concentricity that precision machining operations demand. The internal thread is 1.041 inch-24 and the external thread is 1.242 inch-20, conforming to the established 5C dimensional standard. Machinists, tool-and-die technicians, and CNC operators are the typical end users for this type of workholding component.

This collet is suited for use in manual engine lathes, CNC turning centers, and collet-closer-equipped machines that run the 5C spindle configuration. It is appropriate for production environments and job shop applications where small-diameter round stock in the 5/64 inch range requires secure, repeatable workholding. The steel construction handles the clamping forces and wear cycles typical of continuous machining use without deforming the collet bore over time.

Key Features

• 5/64 inch bore diameter for small round stock workholding
• 0.0005 inch TIR for high concentricity and repeatable part positioning
• 1.041 inch-24 internal thread conforms to 5C standard
• 1.242 inch-20 external thread conforms to 5C standard
• Steel construction for durability under repeated clamping cycles

Compatibility

Designed as a standard 5C round collet replacement or addition for any lathe, collet fixture, or spindle equipment built to accept the 5C collet system.

Installation Notes

Installation and removal of 5C collets should be performed with the machine spindle fully stopped and the machine locked out per OSHA lockout/tagout procedures. Use the appropriate collet closer or draw tube wrench for the specific machine to avoid cross-threading the collet. Inspect the spindle bore and collet taper for chips or burrs before seating, as contamination directly affects TIR. Collet service and workholding setup is typically performed by a machinist or toolroom technician.
