Techniks 04232-04.5 ER32 Collet 4.5 Mm

Product Description

The TECHNIKS 04232-04.5 is an ER32 series collet designed for precision workholding in CNC machining centers, milling machines, and similar rotating spindle equipment. Built to ER32 standards, it accepts a 4.5 mm collet size and delivers a total indicator runout (TIR) of 0.0050 mm, making it suitable for applications where concentricity and tool accuracy are critical. Through-coolant capability allows cutting fluid to pass directly through the collet to the tool tip, supporting chip evacuation and tool life in demanding cutting operations. Machinists and CNC setup technicians are the primary installers.

This collet is used in production and job-shop environments where ER32-compatible toolholders are the standard. Typical applications include end milling, drilling, reaming, and tapping operations in both ferrous and non-ferrous materials. The through-coolant feature makes it well suited for deep-hole drilling and high-speed machining where coolant delivery at the cutting edge is required. It fits any ER32-standard collet chuck or toolholder.

Key Features

• ER32 collet series for broad toolholder compatibility
• 4.5 mm collet size for precise small-diameter tool clamping
• TIR of 0.0050 mm for high concentricity and accuracy
• Through-coolant design channels fluid directly to the cutting edge
• Lightweight at 0.3 pounds for minimal spindle load impact

Compatibility

Designed as a direct-fit replacement for ER32-standard collet chucks and toolholders accepting a 4.5 mm collet size.

Installation Notes

Installation is performed by machinists or CNC toolroom technicians. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing collets. Clean the collet, nut, and chuck bore thoroughly before seating to prevent runout caused by debris. Do not exceed the toolholder manufacturer's torque specifications for the collet nut.
