Value Collection 230-4122 5C Round Steel Collet 11/32

Product Description

The VALUE COLLECTION 230-4122 is a 5C-style round steel collet designed for use in lathes, collet chucks, and other spindle-driven workholding equipment. It accepts round stock at 11/32 inch, delivering a Total Indicator Runout (TIR) of 0.0005 inches for precise, repeatable workpiece centering. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20, conforming to standard 5C geometry. Machined from steel for durability under continuous shop use, this collet suits production turning, milling, and grinding applications where close tolerances matter. Installation and replacement are handled by machinists and toolroom technicians.

This collet is used in any machine tool or fixture that accepts the 5C collet standard — a widely adopted workholding format found in manual lathes, CNC turning centers, indexing fixtures, and collet blocks. It is suited to both job-shop and production environments where round bar stock at 11/32 inch diameter needs to be held concentrically. The steel construction handles the clamping forces typical of light to medium-duty turning and milling operations without deforming under normal use cycles.

Key Features

• 5C collet standard — fits the broad range of lathes, chucks, and fixtures built to this geometry
• Round collet profile accepts 11/32 inch diameter round stock
• 0.0005 inch TIR for tight concentricity and repeatable part location
• 1.041 inches-24 internal thread and 1.242 inches-20 external thread meet standard 5C specifications
• Steel construction resists deformation under clamping loads in production use

Compatibility

Designed as a standard 5C-style replacement collet compatible with machine tools and workholding fixtures built to accept the 5C collet format.

Installation Notes

5C collets are installed and changed by qualified machinists or toolroom technicians. Always de-energize and lock out the machine spindle before changing collets. Inspect the collet closer, draw tube, and spindle bore for chips or burrs before seating the collet, as debris will directly affect runout. Thread engagement and closer draw force should follow the machine tool manufacturer's specifications.
