Techniks 04232-05 ER32 Collet 5mm Through Coolant

Product Description

The TECHNIKS 04232-05 is an ER32 collet designed for precision workholding in CNC machining and milling operations. With a 5mm collet size and a total indicator runout (TIR) of 0.005mm, this collet delivers tight concentricity tolerances essential for accurate cutting and drilling. The overall length is 2 inches with an overall diameter of 1 inch. Built with through-coolant capability, it supports direct coolant delivery to the cutting zone, helping manage heat and extend tool life. Machinists and CNC operators install this collet in ER32-compatible toolholding systems across a range of production and job-shop environments.

This ER32 collet is suited for use in machining centers, milling machines, and lathes that accept the ER32 collet standard. The through-coolant design makes it a practical choice for high-speed or deep-bore applications where coolant-through tooling is required. It fits standard ER32 collet chucks and is appropriate for both production runs and precision prototype work where runout control is a priority.

Key Features

• ER32 collet series for broad compatibility with ER32 toolholding systems
• 5mm collet size for precise small-diameter tool clamping
• TIR of 0.005mm for tight concentricity and accurate machining
• Through-coolant design channels fluid directly to the cutting zone
• 2 inch overall length and 1 inch overall diameter

Compatibility

Designed as a direct-fit replacement for standard ER32 collet chucks and ER32-compatible toolholding systems.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before installing or changing collets, ensure the machine spindle is powered down and fully stopped. Use a proper ER32 collet nut and spanner wrench to seat and torque the collet chuck assembly according to the toolholder manufacturer guidelines. Inspect the collet and chuck bore for debris or damage before installation to maintain rated TIR performance.
