Value Collection 230-4424 5C Expanding Collet

Product Description

The VALUE COLLECTION 230-4424 is a 5C expanding collet machined from steel for use in compatible 5C collet fixtures, chucks, and indexing equipment. Expanding collets grip workpieces from the inside bore rather than the outside diameter, making them the right choice when external surfaces must remain unmarked or when internal-bore workholding is required. The collet features a 1-1/2 inch head diameter, a 3 inch head length, and a concentricity rating of 0.0020 inches TIR, providing consistent, repeatable grip alignment suitable for production turning and grinding applications. At 2.75 pounds, it is a solid, durable tooling component built for shop-floor use.

This expanding collet is suited for manual machining centers, CNC lathes, and rotary indexing setups where internal workholding is needed. It accommodates a minimum grip of 0.7500 inches (3/4 inch) and a maximum grip of 1.4375 inches (1-7/16 inch), covering a practical range for mid-sized bore diameters. Typical users include machinists, tool and die makers, and CNC operators working in job shops or production environments. Installation is performed by qualified machining personnel familiar with 5C collet systems.

Key Features

• Expanding collet design grips workpieces from the internal bore, protecting external surfaces

• 1-1/2 inch head diameter and 3 inch head length
• Grip range from 0.7500 to 1.4375 inches to accommodate varied bore sizes
• Steel construction for durability in production machining environments
• Internal thread size 1.041 inches-24 and external thread size 1.242 inches-20 for standard 5C compatibility

Compatibility

Designed as an OEM-style replacement or direct-fit tooling component for standard 5C collet chucks, fixtures, and rotary indexers that accept expanding-style 5C collets.

Installation Notes

Installation should be performed by a qualified machinist familiar with 5C collet systems. Ensure the spindle or chuck is fully stopped and de-energized before inserting or removing the collet. Inspect the collet seat and threads for debris or damage before seating the collet. Follow the equipment manufacturer's torque and draw-bar guidelines for the specific chuck or fixture in use.
