Value Collection 230-4107 5C Steel Round Collet 7/64

Product Description

The VALUE COLLECTION 230-4107 is a 5C-style steel round collet designed for use in 5C-compatible spindles and collet chucks found on lathes, milling machines, and grinding equipment. Sized at 7/64 inch, it delivers a total indicated runout (TIR) of 0.0005 inch, making it suitable for precision workholding applications where concentricity matters. The collet features a 1.041-24 internal thread and a 1.242-20 external thread, conforming to standard 5C dimensional specifications. Machinists and toolroom technicians install this collet when holding small-diameter round stock for turning, grinding, or secondary operations.

This collet is used in production and jobshop environments wherever 5C spindle tooling is the standard setup. It is appropriate for light to medium-duty workholding of round bar stock at the 7/64 inch diameter. Typical applications include screw machine work, precision turning of small-diameter parts, and fixture-based grinding setups. The steel construction provides durability under repeated clamping cycles in standard shop conditions.

Key Features

• 5C-style round collet for standard 5C spindle compatibility
• 7/64 inch collet bore for small-diameter round workholding
• 0.0005 inch TIR for precision concentricity
• 1.041-24 internal thread per 5C dimensional standard
• 1.242-20 external thread per 5C dimensional standard
• Steel construction for durability under repeated clamping cycles

Compatibility

Designed as a standard 5C-style replacement or additional collet for any machine tool equipped with a 5C-compatible spindle or collet chuck.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with 5C collet systems. Before installing or removing the collet, ensure the machine spindle is fully stopped and locked out per shop lockout/tagout procedures. Inspect the collet and spindle bore for chips or debris before seating the collet, as contamination directly affects runout. Do not exceed the rated collet bore size when chucking workpieces, as overloading will damage the collet and degrade workholding accuracy.
