Value Collection 230-4162 5C Steel Collet 31/32 in

Product Description

The VALUE COLLECTION 230-4162 is a 5C-style steel collet designed to hold round workpieces with a collet size of 31/32 inches. It features a total indicator runout (TIR) of 0.0005 inches, making it suitable for applications where concentricity and precision are critical. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C collet dimensions. This collet is machined from steel for durability under the clamping forces typical of lathe and collet-chuck work. Machinists and toolroom technicians install this type of collet in 5C-compatible spindles, collet closers, and fixtures across manual and CNC turning operations.

This collet is used in production and job-shop machining environments where repeatable part holding is required. It accepts round bar stock or turned workpieces at the 31/32-inch diameter. Typical applications include turning, facing, and secondary operations on screw machines, engine lathes, and collet-chuck equipped CNC lathes. Its standard 5C geometry makes it a common choice in shops already running 5C spindle noses or dedicated collet closers.

Key Features

• 31/32-inch round collet capacity for precise bar and workpiece holding
• 0.0005-inch TIR for high concentricity in turning and finishing operations
• 1.041 inches-24 internal thread conforms to standard 5C specification
• 1.242 inches-20 external thread for standard 5C spindle and closer compatibility
• Steel construction for strength and resistance to deformation under clamping load

Compatibility

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

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle or collet closer is fully stopped and de-energized before inserting or removing the collet. Clean the collet seat and collet body of chips and debris before seating to protect TIR performance. Do not force the collet into the closer; it should seat smoothly by hand before the closer is engaged.
