Value Collection 1230-4229 5C Round Collet 16mm Steel

Product Description

The VALUE COLLECTION 1230-4229 is a 5C round collet machined from steel for use in compatible 5C-style spindle noses and collet chucks. It accepts round workpieces at a 16.00 mm collet size and holds a total indicated runout (TIR) of 0.015 mm, making it suitable for precision turning, grinding, and milling setups. The internal thread measures 1.041 inches-24 and the external thread measures 1.242 inches-20. Machinists and toolroom technicians install this collet as part of a workholding system where consistent concentricity and repeatable clamping are required.

This collet fits standard 5C collet-compatible lathes, rotary indexers, collet blocks, and collet chucks used in production and job-shop machining environments. The round profile is appropriate for bar stock, turned blanks, and cylindrical parts within the collet size range. It is a practical choice for shops running manual or CNC lathes equipped with 5C spindle noses. No specific model compatibility was provided by the manufacturer; verify collet size and thread specifications against your machine or chuck documentation before ordering.

Key Features

• 5C collet style for use with standard 5C-compatible workholding equipment
• Round collet profile designed for cylindrical workpieces
• 16.00 mm collet size for consistent clamping on round stock
• TIR of 0.015 mm for precision concentricity in turning and grinding operations
• Steel construction for durability under repeated clamping cycles
• 1.041 inches-24 internal thread and 1.242 inches-20 external thread for proper spindle engagement

Compatibility

Designed as an OEM-style replacement or standard-service collet for machines equipped with 5C-style spindle noses and collet chucks. Confirm internal and external thread sizes and collet capacity against machine specifications before installation.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. Before inserting or removing a collet, disengage the machine spindle and confirm all motion has stopped. Inspect collet and spindle nose threads for burrs or debris before assembly; damaged threads will affect runout and clamping force. Do not use a collet to clamp workpieces outside its rated size range, as overloading can damage the collet or reduce clamping accuracy.
