Value Collection 1230-4210 5C Round Collet 6.50mm

Product Description

The VALUE COLLECTION 1230-4210 is a 5C round collet machined from steel for use in 5C-compatible collet chucks, closers, and fixture systems. It features a 1.041 in-24 internal thread and a 1.242 in-20 external thread, with a total indicated runout (TIR) of 0.015 mm for consistent workpiece concentricity. Weighing 0.5 pounds, this collet suits production turning, grinding, and milling operations where repeatable part holding is required. Machinists and tool room technicians install these collets in manual and CNC lathes as well as collet blocks on milling machines.

This 5C round collet is sized for workpieces at 6.50 mm and is suited to light and medium-duty machining in job shops, production facilities, and tool rooms. It fits standard 5C spindle noses and collet closers found on most manual lathes and many CNC turning centers equipped with 5C tooling packages. The steel construction withstands the clamping forces and vibration typical of repetitive turning and facing operations.

Key Features

• 5C round collet profile fits standard 5C collet chucks and closers
• 6.50 mm collet size for consistent small-diameter workpiece holding
• Steel construction for durability under repeated clamping cycles
• 1.041 in-24 internal thread and 1.242 in-20 external thread for proper seating
• TIR of 0.015 mm supports accurate concentricity in turning and grinding operations

Compatibility

Designed as an OEM-style replacement or standard tooling addition for machinery equipped with 5C collet spindle systems.

Installation Notes

Installation is performed by qualified machinists or tool room technicians. Power down and lock out the machine spindle before inserting or removing the collet. Inspect the collet taper and spindle bore for chips or burrs before seating. Do not exceed the rated workpiece diameter range, as overloading the collet can cause runout or damage to the spindle nose.
