Value Collection 230-4112 5C Steel Collet 3/16 in Round

Product Description

The VALUE COLLECTION 230-4112 is a 5C-style steel collet machined for round workholding applications in lathes, collet chucks, and grinding fixtures that accept the 5C collet standard. Sized at 3/16 inches, it holds round stock with a total indicated runout (TIR) of 0.0005 inches, providing the concentricity required for precision turning, grinding, and secondary operations. The internal thread is 1.041 inches-24 and the external thread is 1.242 inches-20, conforming to standard 5C geometry. Machinists and toolroom technicians working in job shops, production facilities, or maintenance departments will find this collet a direct-fit replacement or spare for any standard 5C-compatible spindle.

This collet is suited for use in manual lathes, CNC lathes, and collet fixtures where a 5C spindle nose is present. It accepts 3/16-inch round bar stock, making it appropriate for small-diameter turning, threading, and facing operations. The steel construction handles the clamping stresses of both light-finish and moderate-material-removal passes. It is a single-piece unit packaged individually, appropriate for bench stock or direct installation on the machine.

Compatibility

Designed as an OEM-style replacement or spare for any lathe spindle, collet chuck, or collet fixture that accepts the standard 5C collet form factor.

Installation Notes

Installation is performed by a machinist or toolroom technician. The spindle must be fully stopped and the machine powered down before inserting or removing a collet. Inspect the collet taper and the spindle bore for chips or burrs before seating the collet, as contamination will affect runout. Use the appropriate collet closer or drawtube mechanism rated for the 5C standard — do not over-torque the closer beyond the machine manufacturer's recommended procedure.
