Value Collection 1230-4209 5C Round Collet 6.00 Mm

Product Description

The VALUE COLLECTION 1230-4209 is a 5C round collet machined from steel for use in 5C-compatible spindles and collet chucks on lathes, grinders, and milling machines. It holds round workpieces with a collet size of 6.00 mm and provides a total indicator runout (TIR) of 0.015 mm, making it appropriate for precision turning and grinding 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. Machinists and toolroom technicians install this collet as part of standard workholding setups in both production and job-shop environments.

This 5C round collet is suited for manual and CNC lathes, cylindrical grinders, and indexing fixtures that accept the 5C collet system. It is a common workholding solution in machine shops handling round bar stock and small-diameter parts requiring repeatable, concentric clamping. The steel construction provides durability under continuous cutting loads and repeated tool changes.

Key Features

• 5C round collet design compatible with standard 5C spindle noses and collet chucks
• 6.00 mm collet size for small-diameter round workpiece holding
• 0.015 mm TIR for precise, low-runout clamping
• 1.041 inch-24 internal thread for proper engagement with draw tubes
• 1.242 inch-20 external thread for correct spindle seating
• Steel construction for wear resistance under production conditions

Compatibility

Designed as an OEM-style replacement or supplemental collet for machine tools equipped with a standard 5C collet spindle system.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before installing or removing a collet, power down the machine and bring the spindle to a full stop. Ensure the collet, draw tube threads, and spindle bore are clean and free of chips or debris before seating the collet. Do not overtighten the draw tube, as this can damage the collet threads or distort the bore.
