Value Collection 1230-4207 5C Round Collet Steel

Product Description

The VALUE COLLECTION 1230-4207 is a 5C round collet machined from steel for use in 5C-compatible spindles and collet chucks found on lathes, grinders, and rotary indexing fixtures. It features a 1.041 inch-24 internal thread and a 1.242 inch-20 external thread, with a total indicator runout (TIR) of 0.015 millimeters. This collet is sized at 5.00 millimeters and is intended for machinists, toolroom technicians, and production shop operators who require accurate workholding at the spindle. The steel construction provides the rigidity and wear resistance expected in a standard collet application.

This 5C round collet fits standard 5C collet-accepting machine spindles used in manual and CNC turning, cylindrical grinding, and indexing applications. It is suited for light to medium production environments where repeatable part location is required. The 5.00 mm collet size accommodates round stock or tooling shanks at that diameter. No adapter or special tooling is required beyond a 5C-compatible closer or chuck body.

Key Features

• 5C round collet design fits standard 5C spindles and collet chucks
• Steel construction for rigidity and long service life in production environments
• 1.041 inch-24 internal thread for secure closer engagement
• 1.242 inch-20 external thread matches standard 5C spindle interface
• TIR of 0.015 mm for consistent workpiece concentricity
• 5.00 mm collet size for round stock or shank workholding

Compatibility

Designed as a direct-fit replacement or spare for standard 5C collet-accepting spindles and collet chucks on lathes, grinders, and indexing fixtures that use the 5C collet standard.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before inserting or removing the collet. Ensure the spindle bore and collet taper are clean and free of chips or burrs before seating the collet. Do not overtighten the closer beyond hand-snug engagement prior to final machine-specific torque procedure per the equipment manufacturer guidelines.
