Value Collection 530-4318 5C Hex Steel Collet 9/32 in

Product Description

The VALUE COLLECTION 530-4318 is a 5C hex collet machined from steel for use in 5C-compatible spindles and collet closers. It accepts hex stock at 9/32 inch across flats and holds total indicator runout (TIR) to 0.0005 inches, making it suitable for precision turning, milling, and secondary operations on hex bar stock. The 1.041 inch-24 internal thread and 1.242 inch-20 external thread conform to standard 5C tooling dimensions. Machinists and tool room operators use this collet for repeatable workholding on production or job-shop lathes and rotary indexers.

This collet is sized for hex workpieces measuring 9/32 inch and is intended for use in lathes, collet chucks, collet blocks, and rotary fixtures that accept the 5C collet series. It is well suited to production environments requiring consistent grip on hex bar stock for turning, threading, or secondary milling operations. The steel construction provides the rigidity needed for light to moderate cutting loads across a range of metalworking applications.

Installation Notes

Installation should be performed by a qualified machinist familiar with 5C collet tooling. Power down and de-energize the spindle drive completely before inserting or removing the collet. Inspect collet bore and spindle taper for chips or debris prior to seating, as contamination directly affects runout and workholding accuracy. Thread engagement should be smooth and free of binding; forced threading may damage the collet or spindle closer threads.
