Value Collection 230-4141 5C Round Steel Collet 41/64 in

Product Description

The VALUE COLLECTION 230-4141 is a 5C-style round steel collet designed for use in 5C-compatible lathes, collet chucks, and spin fixtures. Machined from steel, it holds round workpieces at a nominal bore of 41/64 inches with a total indicator reading (TIR) of 0.0005 inches, making it suitable for precision turning, grinding, and secondary machining operations. The internal thread measures 1.041 inches at 24 threads per inch, and the external thread measures 1.242 inches at 20 threads per inch. Machinists and toolroom technicians rely on this collet type for repeatable, concentric workholding in production and job-shop environments.

This collet is used in machine shops, tool rooms, and manufacturing cells wherever 5C workholding is the standard. It is appropriate for both manual and CNC-driven 5C collet closers, indexing heads, and rotary fixtures. The round profile makes it the standard choice for bar stock, turned blanks, and cylindrical parts at the 41/64 inch size. It is commonly installed on manual engine lathes, turret lathes, and CNC turning centers equipped with a 5C spindle nose or collet closer.

Key Features

• 41/64 inch nominal bore for round workpieces
• 0.0005 inch TIR for precision concentricity
• 1.041 in-24 internal thread matches standard 5C closer hardware
• 1.242 in-20 external thread for standard 5C chuck and fixture compatibility
• Steel construction for durability in production workholding applications

Compatibility

Designed as an OEM-style replacement and standard fitment for 5C-compatible collet closers, collet chucks, and indexing fixtures accepting round 5C collets.

Installation Notes

5C collets are installed and removed by qualified machinists or toolroom technicians. Always disengage the machine spindle and lock out power before inserting or removing a collet from a closer or chuck. Inspect the collet bore, taper, and threads for chips or damage before seating. Do not force a collet into a closer with a hammer or pry tool, as this can damage the taper seat and degrade TIR performance.
