Value Collection 230-4147 5C Steel Collet 47/64 in

Product Description

The VALUE COLLECTION 230-4147 is a 5C round steel collet sized at 47/64 inch, designed for use in 5C-compatible collet chucks, spin fixtures, and collet blocks found in production machining environments. The collet holds a total indicator runout (TIR) of 0.0005 inches, providing the concentricity required for precision turning, milling, and grinding operations. Internal thread is 1.041-24 and external thread is 1.242-20, conforming to the standard 5C interface. The body is machined from steel for rigidity and long service life under repeated clamping cycles. This collet is installed and serviced by machinists, toolroom technicians, and CNC setup personnel.

This collet is suited for use in manual lathes, CNC turning centers, and 5C indexing or spin fixtures in both job-shop and production settings. It accepts round workpieces at the 47/64-inch nominal size, making it appropriate for bar-feed operations and secondary operations on turned or ground stock. The 5C form factor is one of the most common collet standards in North American machine shops, and this collet fits that existing tooling infrastructure without modification.

Key Features

• 47/64-inch round capacity in the standard 5C collet form factor
• 0.0005-inch TIR for precise workholding concentricity
• 1.041-24 internal thread and 1.242-20 external thread per 5C standard
• Steel construction for durability under repeated clamping loads
• Compatible with 5C collet chucks, blocks, and spin fixtures

Compatibility

Designed as an OEM-style replacement or supplemental collet for any machine tool or workholding fixture that accepts the standard 5C collet interface.

Installation Notes

5C collets are installed and removed by hand or with a collet wrench on the drawbar or closer mechanism; confirm the machine spindle is powered off and at a complete stop before handling. Inspect the collet bore and the spindle taper for chips or burrs prior to installation, as contamination will directly affect TIR. Do not exceed the collet nominal size, as overloading the collet past its rated capacity will distort the split segments and degrade clamping accuracy.
