Omega Products ER32 Collet with Sealed Coolant offers a reliable, high-precision toolholding solution for milling, drilling, and finishing tasks. Designed for round tooling clamping in the 3–20 mm range, it features a high-pressure coolant path and an ultra-tight run-out specification to help you maintain consistent tolerances and superior surface finishes, even during demanding cycles.

Newer versions use a streamlined design with no rubber seal on the nose and feature non-overlapping longitudinal slots to prevent coolant loss at the centre. For optimal performance, ensure you use only round shank tooling with no clamping flats, as flats can compromise the seal and reduce effectiveness.

• Ultra-precise run-out (<10 μm): Delivers tight tolerances and smoother surface finishes, reducing rework and improving part consistency.
• High-pressure coolant sealing up to 120 bar: Integral metal seal keeps coolant in the intended path, enhancing cooling performance and extending tool life under heavy cutting.
• Non-overlapping slots and nose design (no rubber seal on newest versions): Prevents centre coolant loss for reliable cooling and long-term seal integrity, while supporting straightforward, round-shank tooling usage.

This sealed ER32 collet is built to improve workflow on busy shop floors by delivering stable clamping, efficient cooling, and repeatable results. Its robust construction and precise seating help reduce downtime, minimize tool wear, and enable consistent production quality across a range of materials and applications.
