Omega Products ER25 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -15mm

Omega ER25 coolant-sealed collet delivers precise, reliable toolholding for CNC milling and drilling. This standard-precision collet clamps round shank tooling within a 3–16 mm range and includes a coolant seal to help keep the work area clean and leakage-free. Note: some newer versions have no rubber seal on the nose, so check your variant to ensure coolant containment. The design features longitudinal slots that do not overlap at the center, preventing coolant loss during demanding cuts.

• 10 μm run-out for repeatable precision: Delivers tight, consistent tool positioning that improves dimensional accuracy and surface finish across every job.
• Coolant-sealed with non-overlapping slots: The nose seal and slot arrangement minimize coolant leakage, helping keep your spindle cleaner and reducing maintenance time.
• Versatile clamping range and round-shank compatibility: Fits tools from 3 to 16 mm in diameter and requires round shanks for a true seal; tools with clamping flats can compromise performance, and some newer versions may omit the rubber nose seal—select the variant that matches your setup.

With these ER25 coolant-sealed collets, you gain dependable toolholding that supports consistent hole sizes, cleaner coolant management, and faster setups. The ultra-low 10 μm run-out combined with a sealed design and wide clamping range helps you finish parts to spec, reduce downtime, and maintain a smooth workflow in demanding machining applications.
