Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -20mm

The Omega ER32 Collet is a coolant-sealed, standard-precision toolholder designed for demanding milling and drilling tasks. It clamps round-shank tooling securely in a 3–20 mm range while delivering consistent run-out performance for tight tolerances and better surface finish. This model uses a sealed nose design to manage coolant flow; note that newer versions have no rubber seal on the nose, which can influence compatibility with certain tooling setups.

• Ultra-precise run-out (<10 μm): Maintains tight tolerances for repeatable pockets, borings, and finishes, helping you achieve consistent results across jobs.
• Leak-resistant coolant seal design: Longitudinal slots do not overlap at the center, preventing coolant loss and keeping the cutting area cleaner and the tool working reliably longer.
• 3–20 mm clamping range for round shank tooling: Optimized for standard round tooling; use round shanks with no clamping flats to complete the seal—shanks with flats will render the collet ineffective.

Choosing this ER32 coolant-sealed collet supports a smoother workflow, reduces downtime from coolant leaks, and enhances overall machining reliability. With its proven precision and robust construction, you can expect consistent performance, cleaner coolant management, and confident results across a wide range of milling and drilling applications.
