Techniks 04232-08.5 ER32 Collet 8.5mm

Product Description

The TECHNIKS 04232-08.5 is an ER32 series collet designed for precision workholding in CNC machining and milling applications. Built to accept an 8.5mm bore, this collet delivers a Total Indicator Runout (TIR) of 0.0002 inches (0.0050 mm), making it suitable for tight-tolerance operations where concentricity is critical. It features through-coolant capability, allowing coolant to pass directly through the collet to the cutting zone. Machinists, CNC operators, and tool crib technicians working in production or job-shop environments will find this collet a reliable ER32 standard component.

This collet is used in ER32-compatible collet chucks mounted on CNC machining centers, milling machines, lathes with live tooling, and similar machine tool spindles. The ER32 series is one of the most widely adopted collet standards in general metalworking. The 8.5mm bore size accommodates metric tooling shanks of that diameter. Through-coolant support makes it appropriate for drilling and reaming operations where directed coolant flow improves tool life and chip evacuation.

Key Features

• ER32 collet series - compatible with standard ER32 collet chucks
• 8.5mm collet bore size for metric tooling shanks
• TIR of 0.0002 inches (0.0050 mm) for high-precision concentricity
• Through-coolant design supports directed coolant delivery to the cutting zone
• Lightweight at 0.5 pounds for easy handling and quick changeover

Compatibility

Designed as an OEM-style replacement or standard tooling component for use with ER32 collet chucks on CNC machining centers, milling machines, and live-tooling lathes requiring an 8.5mm bore collet.

Installation Notes

Installation and removal of ER collets should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing collets. Use the appropriate ER32 collet nut and spanner wrench to seat and torque the collet chuck assembly per the machine tool manufacturer guidelines. Inspect the collet bore and chuck taper for chips or debris before assembly to maintain the rated TIR performance.
