Value Collection 230-4422 5C Expanding Collet Steel

Product Description

The VALUE COLLECTION 230-4422 is a 5C expanding collet machined from steel for use in lathes, grinders, and other spindle-driven equipment that accept the 5C collet standard. The expanding design grips workpieces from the inside, making it the right choice when external clamping is not practical. It features a head diameter of 1.5 inches, a head length of 2 inches, and a total indicator runout (TIR) of 0.0020 inches, providing the concentricity needed for precision turning and grinding operations. Machinists and toolroom technicians are the primary installers of this collet.

This collet is suited for production turning, second-operation work, and toolroom applications where internal expanding grip is required. The grip range spans from 0.7500 inches minimum to 1.4375 inches maximum, covering a wide range of workpiece bore sizes. It is commonly installed in 5C-compatible collet chucks, collet closers, and indexing fixtures found on manual lathes and CNC turning centers in both job shop and production environments.

Key Features

• Expanding collet design grips workpieces internally for second-operation and bore-holding applications
• Steel construction for durability in production machining environments
• TIR of 0.0020 inches supports concentricity requirements in precision turning and grinding
• Grip range of 0.7500 to 1.4375 inches accommodates a broad range of bore diameters
• Internal thread size of 1.041 inches-24 and external thread size of 1.242 inches-20 for standard 5C tooling compatibility

Compatibility

Designed for use in equipment and fixtures that accept the standard 5C collet form factor, including 5C collet chucks, collet closers, and rotary indexing fixtures.

Installation Notes

Installation is performed by 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 your facility lockout/tagout procedure. Threads should be inspected for cleanliness and damage before seating the collet; do not force a collet that does not thread smoothly. Verify grip range is appropriate for the workpiece diameter before applying clamping force.
