The Omega ER25 Collet with coolant seal delivers ultra-precise toolholding for demanding machining tasks. Built to withstand high-pressure coolant environments, it helps keep coolant and chips away from the spindle while maintaining tight tolerances for consistently accurate results. This makes it a reliable choice for high-speed milling, precision drilling, and applications where surface finish and reliability matter.

• Ultra-precise run-out: Delivers sub-10 μm accuracy to improve part tolerances, repeatability, and overall surface finish in every operation.
• High-pressure coolant seal: Integral metal seal supports coolant pressures up to 120 bar and, with non-overlapping longitudinal slots, minimizes coolant loss for cleaner, cooler, and more productive machining.
• Versatile 3–16 mm clamping range with proper tooling use: ER25 interface provides a wide range of tooling options; newer nose designs reduce maintenance, and for optimal performance, use only round shank tooling with no clamping flats to preserve the seal.

This collet is built to keep your workflow smooth and dependable: precise tool retention, effective cooling under demanding conditions, and a design that minimizes leaks and downtime. Choose the Omega ER25 Collet for reliable performance and consistent results across a range of milling and drilling tasks.
