Value Collection 230-4204 5C Round Collet 4mm

Product Description

The VALUE COLLECTION 230-4204 is a 5C-style round collet machined from steel, designed to hold workpieces in lathes, grinders, and milling fixtures that accept the 5C collet standard. With a 4.00 mm collet size and a total indicated runout (TIR) of 0.015 mm, this collet delivers the concentricity required for precision turning and grinding operations. The 1.041 inch-24 internal thread and 1.242 inch-20 external thread match the standard 5C collet nose geometry. Machinists and tool-room technicians rely on this type of collet for repeatable workholding when running production lots or performing close-tolerance finishing cuts.

This 5C round collet is suited for use on manual engine lathes, CNC turning centers, and bench-top grinders equipped with a 5C collet closer or collet chuck. It is appropriate for both job-shop and production environments where consistent part location is critical. The collet accepts round-profile stock or turned workpieces that match the 4.00 mm bore size. It is a standard replacement or additional collet for shops already operating on the 5C tooling platform.

Key Features

• 5C round collet design compatible with the standard 5C collet system
• 4.00 mm collet bore size for precise small-diameter workholding
• Low TIR of 0.015 mm supports concentricity-critical turning and grinding
• Steel construction for durability under repeated clamping cycles
• 1.041 inch-24 internal thread and 1.242 inch-20 external thread match standard 5C geometry

Compatibility

Designed for use with lathes, grinders, and milling fixtures built to accept the standard 5C collet system.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before inserting or removing a collet, ensure the spindle is fully stopped and the machine is locked out per your shop lockout/tagout procedure. Thread the collet into the collet closer or chuck nose by hand first to confirm thread engagement before applying a collet wrench. Inspect the collet bore and seating taper for chips or burrs before use, as contamination will increase runout and can damage the collet closer.
