Omega Products ER32 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 9mm

The Omega ER32 Collet with coolant-sealed Ultra Precision is built for demanding milling and precision machining where reliable cooling and repeatable toolholding matter. With an ultra-low 10 micron run-out, it helps you achieve tighter tolerances and smoother finishes, even on challenging materials. It clamps a wide range of tool diameters from 3 to 20 mm, making it a versatile choice for a variety of tooling setups.

Newer versions feature a simplified, rubber-free nose seal and an integral metal seal designed to maintain coolant pressure up to 120 bar. The nose and slot geometry are engineered to minimize coolant loss, with longitudinal slots that do not overlap at the center. To preserve the seal’s effectiveness, ensure you use solely round shank tooling with no clamping flats.

• Ultra-Precise 10 μm Run-Out: Delivers tighter tolerances and improved surface finishes for accurate, repeatable machining results across materials.
• High-Pressure Coolant Sealed Design: Integral metal seal supports coolant pressures up to 120 bar and accommodates tool diameters from 3 to 20 mm, reducing overheating and improving tool life.
• Non-Overlapping Slot Geometry & Round Shank Compatibility: Slots don’t cross at the center to prevent coolant leakage; a round-shank tool (no clamping flats) ensures the seal remains effective, with newer noses adopting a rubber-free seal for durability.

This coolant-sealed ER32 collet is designed to keep your workflow uninterrupted: steady, accurate toolholding, reliable cooling under high pressure, and a seal that minimizes leaks. By combining precision run-out with durable sealing geometry, it helps you achieve consistent results, reduce downtime, and extend tool life across a wide range of milling and drilling tasks.
