Techniks 04232-18.5 ER32 Collet 18.50mm Through Coolant

Product Description

The TECHNIKS 04232-18.5 is an ER32 series collet designed for precision workholding in CNC machining and toolholding applications. It accepts a collet size of 18.50mm and delivers a total indicated runout (TIR) of 0.0002 inches (0.0050mm), making it suitable for tight-tolerance operations where concentricity is critical. The collet features through-coolant capability, allowing coolant to be directed to the cutting zone for improved tool life and chip evacuation. Machinists and CNC setup technicians install this collet into compatible ER32 collet chucks on milling machines, lathes, and machining centers.

This collet is appropriate for use in both production and job-shop environments where ER32 toolholding is standard. Through-coolant support makes it well suited for deep-pocket milling, drilling, and boring operations where flood coolant alone does not reach the cutting edge effectively. It is a direct-fit component for any machine spindle or chuck configured for the ER32 collet standard.

Key Features

• ER32 collet series for broad chuck compatibility
• 18.50mm collet size for precise tool shank engagement
• TIR of 0.0002 inches (0.0050mm) for high-concentricity performance
• Through-coolant design directs coolant to the cutting zone
• Compact form factor suited for high-speed spindle applications

Compatibility

Designed as an OEM-style replacement and standard fitment collet for ER32 collet chucks used in CNC milling, turning, and machining center applications.

Installation Notes

ER32 collets are installed and removed by qualified machinists or CNC technicians using an ER32 collet nut and the appropriate spanner wrench. Ensure the spindle is fully stopped and the machine is in a safe locked-out state before changing tooling. Inspect the collet bore and chuck taper for chips or debris before seating the collet. Do not exceed the collet's rated clamping range for the tool shank diameter being held.
