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

The Omega Products ER32 Collet is a coolant-sealed, standard-precision toolholding solution designed for milling and drilling with small round-shank tooling. It delivers tight, repeatable grip and low run-out to improve dimensional accuracy and surface finish across a wide range of materials.

With a clamping range of 3–20 mm, this ER32 collet covers many common small-tool applications in professional shops and hobbyist setups alike. Note that newer versions omit the rubber nose seal, and the design features non-overlapping longitudinal slots to minimize coolant leakage. For the seal to work effectively, use solely round shank tooling with no clamping flats.

• Exceptional run-out control: Delivers precision at or below 10 μm, enabling consistent hole sizes and finishes and reducing rework in your milling and drilling operations.
• Leak‑free coolant seal design: Slots do not overlap at the centre to prevent coolant loss, keeping your work area cleaner and improving tool life; newer versions have no rubber seal on the nose for straightforward maintenance.
• Versatile clamping range for round shanks (3–20 mm): Provides flexible use across a wide selection of small tooling with a secure, wobble-free grip that minimizes downtime and ensures repeatable results.

This collet is built for dependable performance in demanding workshop environments. By maintaining precise toolholding and containing coolant where it belongs, it helps you streamline setups, reduce setup time, and achieve reliable, repeatable results across your milling and drilling tasks.
