Techniks 04232-11/32 ER32 Collet 11/32 Inch

Product Description

The TECHNIKS 04232-11/32 is an ER32 collet sized at 11/32 inch (0.3438 inch decimal) designed for precision workholding in CNC machining and manual milling applications. It features through-coolant capability, allowing coolant to flow directly to the cutting zone for improved tool life and chip evacuation. With a total indicator runout (TIR) of 0.0002 inch, this collet delivers the concentricity required for close-tolerance machining operations. Machinists and tool room technicians install this collet into compatible ER32 collet chucks or toolholders to secure round-shank cutting tools, taps, drills, and reamers during metal removal operations.

This ER32 collet is suited for use in machine shops running CNC machining centers, CNC lathes with live tooling, and manual milling machines equipped with ER32 toolholding systems. The 11/32 inch bore size accommodates tools ground to that shank diameter. Through-coolant support makes it a practical choice for deep-hole drilling, tapping, and high-speed operations where heat and chip buildup are concerns. The 2 inch overall length and 1 inch overall diameter fit standard ER32 chuck specifications.

Key Features

• ER32 collet series - fits standard ER32 chucks and toolholders
• 11/32 inch (0.3438 inch) bore for direct shank tool clamping
• Through-coolant design channels coolant to the cutting edge
• 0.0002 inch TIR for high concentricity and dimensional accuracy
• 2 inch overall length and 1 inch overall diameter

Compatibility

Designed for use with ER32 collet chucks and toolholding systems that accept the standard ER32 collet form factor.

Installation Notes

ER32 collets are installed and removed by machinists using an ER32 collet nut and a compatible spanner wrench. Before changing collets, power down the machine spindle and confirm it has come to a complete stop. Insert the collet into the collet nut before seating it in the chuck body, and torque the nut to the chuck manufacturer's specification using the appropriate wrench. Inspect the collet bore and chuck taper for chips or damage before each installation to maintain TIR performance.
