Value Collection 230-4306 5C Round Collet 1-3/32 in

Product Description

The VALUE COLLECTION 230-4306 is a 5C round collet designed for use in lathes, grinding machines, and other spindle-driven equipment that accept the 5C collet standard. Machined from steel, this collet holds round workpieces at a nominal size of 1-3/32 inches with a total indicator runout (TIR) of 0.0005 inches, making it suitable for close-tolerance turning and grinding operations. The internal thread measures 1.041-24 and the external thread measures 1.242-20, both conforming to standard 5C specifications. Machinists and toolroom professionals install this collet as a direct-fit workholding solution where repeatable, accurate part location is required.

This collet is intended for use in manual and CNC lathes, collet chucks, collet blocks, and indexing fixtures that are set up for the 5C collet system. It is well suited for production turning, light milling, and precision grinding of round bar stock at the 1-3/32 inch nominal diameter. It is commonly found in job shops, toolrooms, and production machine shops handling round stock in that size range.

Compatibility

Designed as an OEM-style replacement or supplemental collet for machine tool spindles and collet chucks built to accept the standard 5C collet form factor.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before inserting or removing a collet, power down the machine and confirm the spindle has come to a complete stop. Use the appropriate 5C collet closer or draw tube for the host machine and ensure the collet seats fully and cleanly in the spindle taper before applying clamping force. Inspect the collet bore and spindle taper for chips or debris prior to installation, as contamination will directly affect runout.
