Value Collection 1230-4226 5C Round Collet 14.50mm

Product Description

The VALUE COLLECTION 1230-4226 is a 5C round collet machined from steel, designed for use in 5C-compatible collet chucks, collet closers, and indexing fixtures on lathes and milling machines. The collet accepts a 14.50mm workpiece diameter and holds to a total indicated runout (TIR) of 0.015mm, providing the concentricity needed for precision turning and grinding operations. The 1.041 inch-24 internal thread and 1.242 inch-20 external thread conform to standard 5C collet geometry. This is a shop-floor replacement or additional-inventory collet suited for use by machinists and toolroom technicians working with round stock.

This collet is intended for round workpieces in 5C collet systems found in manual lathes, CNC turning centers with 5C spindles, and rotary indexing heads. Typical applications include holding bar stock for turning, threading, and facing operations in both production and jobbing environments. The steel construction handles the clamping forces and repeated use cycles common in high-volume machining cells as well as low-volume toolroom work.

Key Features

• 5C round collet profile fits standard 5C collet chucks and closers
• 14.50mm collet size for precise round-stock workholding
• TIR of 0.015mm for consistent concentricity in turning and grinding
• 1.041 inch-24 internal thread per standard 5C specification
• 1.242 inch-20 external thread per standard 5C specification
• Steel construction for durability under repeated clamping cycles

Compatibility

Designed as a standard 5C round collet replacement suitable for use in any 5C-compatible collet chuck, collet closer, or rotary indexing fixture that accepts round collets.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing the collet, ensure the machine spindle is fully stopped and the collet closer or chuck is in the open position. Inspect the collet bore and spindle taper for chips or debris before seating the collet, as contamination directly affects runout. Do not force the collet into the spindle nose; proper thread engagement should be smooth and hand-tight before actuating the closer.
