Value Collection 530-4232 5C Square Collet 1/2 in

Product Description

The VALUE COLLECTION 530-4232 is a 5C-style square steel collet sized for 1/2-inch square stock. It is designed for use in 5C collet chucks, closers, and indexing fixtures found on lathes, rotary tables, and collet blocks. The collet holds square workpieces with a total indicator runout (TIR) of 0.0005 inches, providing accurate, repeatable part location during turning, milling, or secondary operations. Internal thread size is 1.041 inches-24 and external thread size is 1.242 inches-20, conforming to standard 5C dimensional specifications. Machinists and tool-room technicians install and use this collet in production and job-shop environments.

This collet suits light to medium machining operations where square stock must be held concentrically and indexed with precision. Typical applications include lathe turning of square bar stock, collet-block setups for milling operations on square workpieces, and rotary indexing fixtures. It is appropriate for both manual and CNC lathes equipped with a 5C spindle nose or draw-tube closer. The 0.0005-inch TIR rating makes it well-suited for close-tolerance work where part runout directly affects finished dimensions.

Key Features

• 5C collet form factor fits standard 5C chucks, collet blocks, and closers
• Square bore accepts 1/2-inch square stock
• 0.0005-inch TIR for accurate, repeatable workpiece location
• 1.041 inches-24 internal thread and 1.242 inches-20 external thread meet standard 5C specs
• Steel construction provides durability under repeated clamping cycles

Compatibility

Designed as a standard 5C-pattern replacement or additional collet for any lathe, collet fixture, or indexing device that accepts 5C collets with a 1.242 inches-20 external thread.

Installation Notes

Installation is performed by machinists or tool-room technicians. Before installing or changing collets, ensure the machine spindle is fully stopped, the power is locked out, and the draw tube or closer is fully released. Inspect collet bore and seating surfaces for chips or burrs before seating the collet in the closer, as debris will directly affect TIR. Do not exceed the collet manufacturer's recommended clamping force, as overtightening a square collet on stock that is over or undersized can damage the collet or closer.
