Value Collection 230-4116 5C Round Steel Collet 1/4 Inch

Product Description

The VALUE COLLECTION 230-4116 is a 5C round steel collet sized at 1/4 inch, designed for use in 5C-compatible lathes, collet chucks, and indexing fixtures. This collet holds round workpieces with a total indicated runout (TIR) of 0.0005 inches, making it suitable for precision turning, grinding, and second-operation work where concentricity is critical. 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, this collet delivers the rigidity and wear resistance expected in production and job-shop environments. Machinists and toolroom technicians are the primary installers.

This collet is used in manual and CNC lathes, rotary indexers, spin fixtures, and collet blocks that accept the 5C collet standard. It is suited for holding 1/4-inch round bar stock, pins, and turned parts during light to moderate machining operations. Typical applications include production turning, tool and die work, and precision grinding setups where repeatable part location is required. The round collet profile accommodates cylindrical workpieces only.

Key Features

• 1/4 inch capacity for round workpieces in standard 5C collet systems
• 0.0005 inch TIR for high concentricity and repeatable workholding accuracy
• Steel construction for rigidity and durability in production environments
• 1.041 inch-24 internal thread and 1.242 inch-20 external thread match standard 5C geometry
• Compatible with lathes, collet chucks, rotary indexers, and collet blocks accepting 5C tooling

Compatibility

Designed as an OEM-style replacement or standard fitment for machinery and fixtures that accept the 5C collet standard with round-profile collets.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with 5C collet systems. Ensure the spindle or collet chuck is fully de-energized and brought to a complete stop before inserting or removing the collet. Inspect the collet bore and seating taper for chips or debris prior to installation, as contamination will degrade TIR performance. Do not exceed the collet's rated capacity, as overloading can damage both the collet and the workholding equipment.
