Omega Products ER32 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 11mm

The Omega ER32 Collet with coolant seal is a precision toolholding solution for ER32 spindles that require direct high‑pressure cooling. It’s designed for engineers, machinists, and workshop environments where consistent run‑out and reliable coolant delivery are essential for clean finishes and longer tool life.

Designed for demanding machining, this collet supports coolant pressures up to 120 bar and delivers tools securely within a 3–20 mm clamping range. It achieves ultra‑precise run‑out of less than 10 μm, helping you maintain tight tolerances across a variety of milling and drilling operations. Newer versions feature a nose seal with no rubber seal, and the design uses non‑overlapping longitudinal slots to prevent coolant leakage. To ensure the seal functions correctly, use only round‑shank tooling with no clamping flats—the presence of flats can render the seal ineffective.

• Ultra‑precise run‑out (<10 μm): Ensures tight concentricity for repeatable milling, drilling, and finishing passes.
• High‑pressure coolant integrity: Integral metal seal supports coolant pressures up to 120 bar, delivering coolant directly to the cutting edge and reducing chip buildup.
• Durable, leakage‑resistant design: Non‑overlapping slots minimize coolant loss; newer versions have no rubber nose seal. For best results, use only round‑shank tooling with no clamping flats to maintain a reliable seal.

Together, these features provide reliable accuracy, efficient cooling, and reduced downtime in everyday machining. The robust sealing design supports demanding operations, giving you consistent results, fewer reworks, and a smoother workflow across a wide range of tooling and applications.
