Value Collection 230-4153 5C Steel Collet 53/64 in

Product Description

The VALUE COLLECTION 230-4153 is a 5C round steel collet sized at 53/64 inch, designed for use in 5C-compatible lathes, collet chucks, and spin fixtures found in machine shops and production turning environments. The collet holds a total indicator runout (TIR) of 0.0005 inches, providing the concentricity required for precision turning, milling, 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 directly into 5C-compatible spindles and closers. It is made from steel for durability under repeated clamping cycles.

This collet is suited for precision machining applications where consistent workpiece runout is critical. It fits standard 5C collet-compatible machines used in job shops, production floors, and toolroom environments handling round bar stock at the 53/64 inch nominal diameter. The 5C style is one of the most widely used collet systems in North American machine shops, making this a common replacement or additional-capacity collet for shops running a range of bar diameters.

Key Features

• 53/64 inch nominal bore diameter for round workpiece clamping
• 0.0005 inch TIR for high-concentricity holding
• 1.041 inch-24 internal thread matches standard 5C closer systems
• 1.242 inch-20 external thread for positive spindle engagement
• Steel construction for long service life under repeated clamping loads
• 5C style fits a broad range of compatible lathes, chucks, and fixtures

Compatibility

Designed as a standard 5C-style round collet for use in 5C-compatible lathe spindles, collet chucks, indexers, and spin fixtures. Specific machine compatibility depends on the equipment manufacturer's 5C acceptance. No specific model compatibility data was provided in the product input.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing the collet, ensure the machine spindle is fully stopped and all motion has ceased. Thread the collet into the closer or chuck body by hand first to confirm clean thread engagement before applying any tooling force. Inspect the collet bore and seating taper for chips or debris prior to installation, as contamination will directly affect runout performance.
