Meet the Omega ER32 Collet with a high‑pressure coolant seal—designed for CNC milling and drilling where precision and coolant control matter. It delivers ultra‑precise run‑out under 10 microns, helping maintain tight tolerances and smooth finishes across passes. This collet is ideal for engineers, machinists, hobbyists, and shops that demand reliable performance in demanding cutting conditions.

• Ultra-precise run‑out (<10 μm): Supports repeatable accuracy and superior surface finish, reducing rework and scrap across jobs.
• High‑pressure coolant sealing up to 120 bar (rubber-seal-free nose in newer versions): Keeps coolant where it’s needed for effective cooling and chip evacuation, even under heavy cutting.
• Leak‑proof seal design with non‑overlapping slots: Prevents coolant loss at the center for cleaner operation; use only round shank tooling with no clamping flats to maintain the seal.

In everyday use, this ER32 coolant‑sealed collet offers reliable performance with a broad 3–20 mm tool range, minimizing downtime and helping you achieve consistent results job after job. The combination of precise run‑out, robust coolant containment, and durable all‑metal construction makes it a dependable choice for demanding machining tasks.
