Omega Products ER32 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 5mm

Omega ER32 Collet with High-Pressure Coolant Sealed design delivers ultra-precise toolholding for milling and drilling. Built for demanding shops, it provides a tight run-out and a broad clamping range to keep tooling accurately centered during high-load cuts.

Designed for high-speed, coolant-intensive operations, this collet features an integral metal seal engineered to withstand coolant pressures up to 120 bar. The non-overlapping longitudinal slots at the centre help minimize coolant loss, while newer versions remove the rubber seal on the nose for improved durability. For optimal sealing, use only round shank tooling with no clamping flats; tools with flats will render the seal ineffective.

• Ultra-precise run-out: Maintains accuracy with run-out under 10 μm, helping you achieve consistent dimensions and smoother surface finishes across demanding workpieces.
• High-pressure coolant sealing: Integral metal seal supports coolant up to 120 bar, delivering efficient cooling and helping extend tool life during heavy-cutting applications.
• Rubber-free nose design with proper tooling: Newer noses enhance durability by removing the rubber seal; for best results, pair with round shank tooling (no flats) to preserve reliable sealing and performance.

This ER32 coolant-sealed collet delivers reliable, repeatable performance in high-pressure cooling environments. By combining precise clamping, robust sealing, and careful compatibility with round-shank tools, it helps reduce downtime, improve cut quality, and sustain productivity across a wide range of milling and drilling tasks.
