Value Collection 230-4223 5C Round Collet 23mm

Product Description

The VALUE COLLECTION 230-4223 is a 5C round collet machined from steel for use in standard 5C collet chucks, closers, and fixtures found on lathes, grinders, and milling machines. The collet measures 23.00 mm in collet size and holds a total indicated runout (TIR) of 0.015 mm, making it suitable for precision workholding applications where concentricity matters. 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. This is a general-purpose round-profile collet intended for machinists and toolroom technicians working with 5C-compatible equipment.

5C round collets are used in both manual and CNC turning centers, bench lathes, and spin fixtures in job shops, production facilities, and toolrooms. This collet accepts round stock or round shanked tooling and is suited for light to moderate production workholding. The 5C system is one of the most widely adopted collet standards in North American machine shops, and this collet is a direct-fit replacement for worn or damaged round 5C collets in that ecosystem.

Compatibility

Designed as a standard-profile replacement for 5C round collets used in 5C-compatible collet chucks, collet closers, and workholding fixtures on lathes, grinders, and milling machines.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with 5C collet systems. Before installing or removing the collet, ensure the spindle is fully stopped and the machine is powered down or locked out per applicable OSHA lockout/tagout procedures. Thread engagement should be smooth and free of debris — inspect both the collet threads and the chuck threads for wear or contamination before seating. Do not force the collet into the closer; if resistance is felt, inspect for thread damage or incorrect collet size.
