Value Collection 230-4209 5C Round Collet 9mm

Product Description

The VALUE COLLECTION 230-4209 is a 5C round collet machined from steel for use in 5C-compatible spindles and collet closers found on lathes, milling machines, and grinding equipment. The collet accepts a 9.00 mm workpiece diameter and features an internal thread size of 1.041 inches-24 and an external thread size of 1.242 inches-20, allowing proper engagement with standard 5C collet closer mechanisms. Total indicator runout (TIR) is rated at 0.015 mm, providing the concentricity required for precision turning and grinding operations. Machinists and tool room technicians are the primary users of this type of workholding component.

This 5C round collet is suited for machine shops, tool rooms, and production environments running lathes or milling machines equipped with 5C spindle noses or collet chucks. It is appropriate for holding round bar stock or round-shank tooling up to 9.00 mm in diameter. The steel construction handles the clamping forces and repeated use cycles typical in both job shop and production machining settings.

Key Features

• 5C round collet configuration for standard 5C-compatible spindles and closers
• 9.00 mm collet size for round workpieces and bar stock
• TIR of 0.015 mm for precision concentricity in turning and grinding
• Internal thread size: 1.041 inches-24
• External thread size: 1.242 inches-20
• Steel construction for durability under repeated clamping cycles

Compatibility

Designed as a replacement or supplemental collet for lathes, milling machines, and grinding equipment fitted with standard 5C collet spindles and closers.

Installation Notes

Installation is performed by machinists or tool room technicians. Before inserting or removing the collet, confirm the machine spindle is fully stopped and the collet closer is disengaged. Thread the collet into the closer by hand first to verify clean thread engagement before applying the closer handle or draw tube. Inspect the collet bore and seating surfaces for chips or burrs prior to each use to maintain rated TIR.
