Value Collection 230-4146 5C Steel Collet 23/32 in

Product Description

The VALUE COLLECTION 230-4146 is a 5C round collet machined from steel for use in 5C-compatible spindles and collet chucks on lathes, milling machines, and grinding equipment. Sized at 23/32 inch, it holds round workpieces with a total indicator runout (TIR) of 0.0005 inch, making it suitable for precision turning and finishing 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 select this collet when consistent concentricity and repeatable workholding are required on round stock.

This collet is intended for use in machine shop environments where 5C-standard workholding is required. Typical applications include CNC lathe operations, manual turning, cylindrical grinding, and secondary operations on round bar stock measuring 23/32 inch in diameter. It is well suited for production runs and job-shop setups where quick collet changes and accurate part positioning are priorities. Installation requires a 5C-compatible collet closer or chuck body.

Compatibility

Designed as a standard 5C-pattern round collet compatible with 5C collet chucks, spindle noses, and collet closers that accept the 5C form factor.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Power down and lock out the machine spindle before inserting or removing the collet. Ensure the collet bore, spindle taper, and chuck threads are clean and free of chips or burrs before seating the collet. Do not exceed the rated bore size, as overloading a collet can cause workpiece slippage or damage to the threading.
