Engineers, machinists, tradespeople, and hobbyists who demand true precision in high‑pressure coolant milling will value the Omega ER40 Collet. This coolant‑sealed, ultra‑precision ER40 collet is designed to grip tooling securely with exceptional run‑out control, helping you achieve consistent cuts and superior surface finishes. It clamps tools within a 3–26 mm range and supports high‑pressure cooling up to 120 bar, making it a reliable choice for demanding applications. Newer versions feature a nose without a rubber seal for streamlined performance.

• Ultra‑precise run‑out with coolant seal: Delivers <10 μm accuracy and incorporates an integral metal seal to keep coolant precisely where it belongs, improving stability and finish under high‑pressure operation.
• High‑pressure cooling capability: Engineered for up to 120 bar, providing effective cooling and efficient chip evacuation during aggressive milling to extend tool life and maintain consistent performance.
• Non‑overlapping slot design for reliable sealing: Longitudinal slots do not overlap at the centre to prevent coolant loss; for best results, use only round shank tooling with no clamping flats to ensure the seal remains effective across the 3–26 mm range.

This combination translates to tighter tolerances, reduced downtime, and more predictable results in a wide range of machining tasks. By delivering consistent gripping force, improved coolant containment, and compatible tooling requirements, the Omega ER40 Collet helps you maintain smooth workflows, fewer interruptions, and higher quality outcomes with every cut.
