Techniks 04232-22 ER32 Collet 22mm Through Coolant

Product Description

The TECHNIKS 04232-22 is an ER32 series collet designed for precision workholding in CNC machining and toolholding applications. Built to a 22mm collet size, this collet holds a total indicator runout (TIR) of 0.0002 inches (0.0050 mm), making it well-suited for operations where concentricity directly affects finish quality and tool life. Through-coolant capability allows cutting fluid to pass directly through the collet, supporting higher-speed operations and extended tool life in demanding cutting environments. Machinists, CNC operators, and toolroom technicians install and use ER32 collets in everyday production and precision machining work.

The ER32 collet series is widely used in milling, drilling, tapping, and reaming applications on CNC machining centers, manual mills, and multi-axis equipment. This 22mm collet is a standard size within the ER32 range and fits any ER32-compatible collet chuck or toolholder. The through-coolant design makes it a practical choice for shops running high-pressure coolant systems where direct coolant delivery to the cutting zone is required for chip evacuation and thermal control.

Key Features

• ER32 collet series for broad compatibility with ER32 toolholders and collet chucks
• 22mm collet size for consistent gripping across compatible shank diameters
• 0.0002 inch (0.0050 mm) TIR for high concentricity and precision runout control
• Through-coolant design supports high-pressure coolant delivery to the cutting zone
• Lightweight at 0.5 pounds for easy handling during toolchanges

Compatibility

Designed as a direct-fit replacement or standard addition for any ER32-compatible collet chuck or toolholder accepting a 22mm collet.

Installation Notes

ER32 collets are installed and removed by qualified machinists or toolroom technicians using the appropriate ER32 collet nut and spanner wrench. Always ensure the collet chuck and collet bore are clean and free of chips or debris before seating the collet, as contamination directly affects runout. Do not exceed the collet's rated clamping range, and verify torque on the collet nut per the toolholder manufacturer's guidelines. Inspect the collet for wear or damage before each use, as a worn collet will degrade TIR performance.
