Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -8mm

The Omega ER32 Collet with coolant-seal delivers precise, coolant-tight clamping for ER32 tool holders. It’s designed for engineers, machinists, and hobbyists who need reliable performance in milling and drilling.

With a clamping range of 3–20 mm, it grips round-shank tooling securely and helps keep coolant contained, protecting tools and workpieces from leaks. Newer versions feature a streamlined nose design with no rubber seal, relying on the non-overlapping slot geometry to minimize coolant loss.

• Coolant-sealed, non-overlapping slots: The longitudinal slots do not overlap at the center, preventing coolant loss and helping keep the work area clean during flood cooling. Newer versions omit the nose rubber seal, leaning on the slot geometry for reliable sealing.
• Ultra-precise run-out (<10 μm): Delivers consistent, tight tolerance to improve part accuracy, surface finish, and tool life in demanding milling and drilling tasks.
• Broad 3–20 mm clamping range with round-shank tooling: Accommodates a wide range of tools with secure grip, while requiring round-shank tooling (no clamping flats) to maintain seal integrity and reliable performance.

This coolant-sealed ER32 collet supports cleaner coolant management, more repeatable results, and smoother workflows across a variety of machining applications. Its combination of tight run-out, robust sealing geometry, and versatile clamping range helps you reduce setup time, minimize rejects, and maintain consistent performance in both professional shops and DIY setups.
