Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -14mm

Omega Products ER32 Collet Coolant Sealed Standard Precision with sub-10 micron run-out is a precision tool holder designed for milling and drilling with coolant. This 14mm interface collet delivers a stable grip on round-shank tooling, helping you achieve tight tolerances and clean finishes in production and hobby work.

Newer versions have no rubber seal on the nose, but the design continues to prevent coolant loss thanks to non-overlapping longitudinal slots at the center.

• Sub-10 μm run-out: Delivers precise, repeatable grip with tight tolerances and smoother surface finishes, reducing part deviation and finish defects.
• Non-overlapping slots for coolant integrity: The slots do not overlap at the center, preventing coolant leaks and keeping the work area clean and reducing downtime for cleanup.
• Wide 3–20 mm clamping range; round-shank compatibility: Supports a broad range of tooling sizes with secure grip when used with round shanks; for optimal performance, use only round-shank tooling with no clamping flats to preserve the seal.

This coolant-sealed ER32 collet helps you streamline setup and improve results. With ultra-tight run-out, you get consistent tolerances across parts and better finishes; the robust sealing design minimizes coolant leakage and mess, speeding cleaning and reducing downtime. The broad clamping range lets you switch between common tooling sizes without swapping holders, making workflows smoother and more efficient—whether you’re in a high-production environment or a hands-on workshop.
