Techniks 04232-15 ER32 Collet 15mm Through Coolant

Product Description

The TECHNIKS 04232-15 is an ER32 series collet designed for precision workholding in CNC machining centers, milling machines, and similar rotating spindle equipment. With a 15mm collet size and a total indicator runout (TIR) of 0.0050mm, this collet delivers the tight concentricity tolerances demanded in production and toolroom environments. Through-coolant capability allows cutting fluid to reach the tool tip directly, supporting higher cutting speeds and extended tool life. Weighing 0.3 pounds, it is a standard single-unit replacement or addition to an existing ER32 toolholding setup. Machinists and CNC operators are the primary installers of this component.

This collet is suited for use in residential shop, commercial production, and industrial machining environments wherever an ER32-compatible toolholder or collet chuck is in use. It accepts 15mm shank tooling and is appropriate for drilling, milling, reaming, and tapping operations where coolant delivery through the spindle is available. Typical applications include production CNC milling and machining center work where consistent runout control is critical to part quality.

Key Features

• ER32 collet series for broad compatibility with ER32 toolholders and collet chucks
• 15mm collet size accommodates 15mm shank cutting tools
• TIR of 0.0050mm ensures high concentricity for precision machining
• Through-coolant design channels cutting fluid directly to the tool tip
• Lightweight at 0.3 pounds for easy handling and quick changeout

Compatibility

Designed as an OEM-style replacement or upgrade collet for use in any ER32-standard collet chuck or toolholder accepting 15mm collets.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. The spindle must be powered down and the machine placed in an E-stop or lockout/tagout state before changing collets. Use the appropriate ER32 collet nut and spanner wrench to seat and torque the collet chuck assembly per the toolholder manufacturer guidelines. Inspect the collet bore and seating taper for chips or debris before installation to maintain TIR performance.
