Engineered for demanding milling and drilling tasks, the Omega ER32 Collet Coolant Sealed Ultra Precision delivers exceptional toolholding with ultra-low run-out. For shops that require repeatable accuracy and clean cooling, this collet keeps tools aligned and coolant focused at the cutting edge.

Designed for a 10 mm shank interface and a clamping range of 3–20 mm, it supports high-pressure coolant up to 120 bar. Newer versions remove the rubber nose seal, relying on robust metal-to-metal sealing. The center is engineered with non-overlapping longitudinal slots to prevent coolant loss, helping maintain consistent pressure during heavy cuts. Please ensure you are using solely round shank tooling with no clamping flats to complete the seal — tooling with flats will render these collets ineffective.

• Ultra‑precise run‑out (<10 μm): Maintains exact alignment under load for repeatable accuracy, smoother finishes, and longer tool life.
• High‑pressure coolant seal (up to 120 bar): Keeps coolant directed to the cut, improving cooling, chip evacuation, and overall tool performance in demanding applications.
• Non‑overlapping slot design (round‑shank only): Prevents coolant loss at the center for reliable sealing; compatibility requires round shanks with no flats.

This sealed ER32 collet setup helps you sustain tight tolerances, maximize cooling efficiency, and minimize downtime in production environments. With proven run-out control and a rugged sealing system, you can expect repeatable results across a broad range of milling and drilling tasks, delivering cleaner finishes and more consistent performance over time.
