The Omega ER32 Collet with a sealed coolant interface is engineered for precision milling and drilling in demanding environments. It delivers ultra-precise tool holding with run-out under 10 microns, making it suitable for engineers, machinists, hobbyists, and production floors that rely on repeatable accuracy and clean coolant management. Designed to perform under high-pressure cooling, this collet helps you achieve consistent results across a wide range of tools.

• Ultra-precise run-out: Achieves less than 10 μm run-out for repeatable, high-accuracy results across multiple passes and tool types.
• High-pressure sealing up to 120 bar: Integrated metal seal ensures reliable cooling and chip evacuation in demanding machining conditions.
• Leak-free, non-overlapping slot design: Longitudinal slots do not overlap at the centre to prevent coolant loss; uses only round shank tooling with no clamping flats to maintain the seal.

Designed with a clamping range of 3–20 mm and an emphasis on durability, this collet is built to withstand rigorous high-pressure coolant environments. Newer versions feature improved longevity with no rubber seal on the nose, reducing maintenance and potential failure points. When used as intended—with round shank tools and no flats—you’ll experience reliable performance, reduced downtime, and tighter tolerances that translate into better overall part quality.
