Techniks 04232-05.5 ER32 Collet 5.50mm

Product Description

The TECHNIKS 04232-05.5 is an ER32 series collet designed for precision workholding in CNC machining and milling applications. Built to a 5.50mm collet size, it delivers a total indicator runout (TIR) of 0.0002 inches (0.0050mm), making it suitable for high-accuracy toolholding where concentricity is critical. The collet features through-coolant capability, allowing coolant to pass directly through to the cutting tool for improved chip evacuation and thermal management. Machinists and CNC operators install this collet into compatible ER32 collet chucks as part of standard tooling setups.

This collet is used in residential shop, industrial, and production machining environments where ER32-standard toolholding is required. It is appropriate for milling, drilling, tapping, and reaming operations that demand consistent grip force and minimal runout. The through-coolant design makes it especially well-suited for deep-hole drilling and high-speed machining where coolant delivery at the cutting edge improves tool life and surface finish. Installation is performed by qualified machinists or CNC setup technicians.

Key Features

• ER32 collet series for broad chuck compatibility
• 5.50mm collet size for precise tool clamping
• TIR of 0.0002 inches (0.0050mm) for high-concentricity toolholding
• Through-coolant design supports direct coolant delivery to the cutting zone
• Lightweight at 0.5 pounds for easy handling during tool changes

Compatibility

Designed as a standard ER32-series collet for use with compatible ER32 collet chucks and toolholding systems.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing collets. Clean the collet, nut, and chuck bore thoroughly before seating to prevent runout caused by debris. Do not exceed the collet clamping range or overtighten the collet nut, as this can damage the collet or reduce accuracy.
