Techniks 04232-08 ER32 Collet 8mm Through Coolant

Product Description

The TECHNIKS 04232-08 is an ER32 series collet designed for precision workholding in CNC machining and toolholding applications. With a collet size of 8.00 mm and a total indicator runout (TIR) of 0.0050 mm, this collet delivers the accuracy required for close-tolerance machining operations. Through-coolant capability allows cutting fluid to pass directly through the collet, improving chip evacuation and tool life at the cutting zone. Machinists and CNC setup technicians working in production or job-shop environments rely on ER32 collets for reliable, repeatable clamping of end mills, drills, reamers, and other shank tooling.

The 04232-08 fits standard ER32 collet chucks and toolholders used on CNC machining centers, lathes with live tooling, and manual milling machines. The ER32 series is one of the most widely used collet standards in the industry, making this collet a common replacement or expansion component in shops running a variety of machine tool platforms. It is suited for both roughing and finishing operations where runout control is critical.

Key Features

• ER32 collet series for broad compatibility with standard ER32 toolholders
• 8.00 mm collet size for accurate clamping of 8 mm shank tooling
• TIR of 0.0050 mm for high-precision runout control
• Through-coolant design supports direct coolant delivery to the cutting edge
• Lightweight at 0.3 pounds for easy handling during tool changes

Compatibility

Designed as an OEM-style replacement or addition for use with standard ER32 collet chucks and toolholding systems.

Installation Notes

Installation is performed by a machinist or CNC toolroom technician. Ensure the collet chuck and spindle are fully stopped and de-energized before inserting or removing collets. Clean the collet, nut, and chuck bore thoroughly before seating to prevent runout caused by contamination. Use a calibrated torque wrench and the appropriate ER32 collet nut spanner to achieve proper clamping force without overloading the collet or nut.
