Techniks 04232-03 ER32 Collet 3mm Through Coolant

Product Description

The TECHNIKS 04232-03 is an ER32 series collet designed for precision workholding in CNC machining and toolholding applications. With a 3.00 mm collet size and a total indicator runout (TIR) of 0.0050 mm, this collet delivers the tight tolerances demanded in high-accuracy cutting operations. Through-coolant capability allows coolant to pass directly through the collet body, improving chip evacuation and tool life at the cutting zone. At 0.3 pounds, it is a compact, lightweight component suited for both production shops and toolroom environments. Machinists and CNC operators install this collet into compatible ER32 collet chucks and toolholders.

The 04232-03 is intended for use in ER32 collet chucks mounted on CNC machining centers, milling machines, lathes with live tooling, and similar machine tool spindles. The through-coolant feature makes it particularly well suited for deep-hole drilling, reaming, and other operations where directing coolant to the tool tip is critical for part quality and tool longevity. This collet accepts 3.00 mm diameter round shanks and is a standard production-grade component for shops running metric tooling programs.

Key Features

• ER32 collet series for broad compatibility with ER32 chucks and toolholders
• 3.00 mm collet size for metric tooling applications
• Through-coolant design channels coolant directly to the cutting edge
• TIR of 0.0050 mm for precision runout performance
• Lightweight at 0.3 pounds for easy handling and fast tool changes

Compatibility

Designed as a standard ER32 series collet for use in any ER32-compatible collet chuck or toolholder.

Installation Notes

Installation is performed by machinists or CNC setup technicians. Before installing or removing the collet, ensure the machine spindle is fully stopped and the machine is placed in a safe, locked-out state per shop safety procedures. Insert the collet into the ER32 collet nut before threading onto the chuck body, following the toolholder manufacturer's torque guidelines. Inspect the collet bore and chuck taper for chips or damage before each use to maintain runout accuracy.
