Techniks 04232-11 ER32 Collet 11mm Through Coolant

Product Description

The TECHNIKS 04232-11 is an ER32 series collet designed for precision workholding in CNC machining and toolholding applications. It accepts an 11mm bore size and features through-coolant capability, allowing cutting fluid to pass directly to the tool tip for improved chip evacuation and thermal management. With a total indicator runout (TIR) of 0.005mm, this collet delivers the dimensional accuracy required for tight-tolerance milling, drilling, and tapping operations. It is installed by machinists and CNC setup technicians in production and job-shop environments.

This collet is suited for use in ER32-compatible collet chucks on CNC machining centers, lathes with live tooling, and manual milling machines. The ER32 series is a widely adopted standard in both light and heavy-duty cutting applications across industries that demand consistent tool concentricity and reliable clamping force. The through-coolant design makes it particularly effective in deep-hole drilling and high-speed machining scenarios where coolant delivery at the cutting edge is critical.

Key Features

• ER32 collet series for broad compatibility with ER32 chuck systems
• 11mm bore size accommodates metric shank tooling
• Through-coolant design directs fluid to the cutting edge
• 0.005mm TIR for high-precision runout control
• Compact form factor suitable for high-speed spindle applications

Compatibility

Designed for use with ER32-standard collet chucks. Verify chuck series and bore size requirements before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing collets. Use the appropriate ER32 collet nut and spanner wrench to achieve proper seating and clamping torque. Inspect the collet and chuck bore for chips or debris before assembly, as contamination can affect runout performance.
