Omega Products ER40 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -10mm

The Omega ER40 Collet Coolant Sealed Standard Precision is a high‑precision tool holder designed for ER40 tooling. It delivers run-out of less than 10 μm, helping you maintain tight tolerances and achieve superior surface finishes during milling and drilling. The coolant‑sealed design keeps coolant where it belongs, reducing splash and prolonging tool life.

• Sub-10 μm run-out with coolant seal: Maintains exact gripping accuracy for consistent cuts and cleaner finishes, even at higher feed rates.
• Broad 3–26 mm clamping range: Versatile holding for a wide range of round shank tooling with a single collet system.
• Slot design prevents coolant loss: Longitudinal slots do not overlap at the centre to minimize coolant leakage; for best sealing, use only round shank tooling with no clamping flats.

This collet supports reliable, repeatable performance across demanding milling and drilling tasks. By combining precise grip, versatile tooling compatibility, and a leak‑resistant seal, it helps you reduce setup time, minimize downtime, and achieve consistent results with every job.
