The Omega Products ER32 Collet Coolant Sealed Ultra Precision is a precision toolholding solution designed for milling centers and drilling applications that demand accurate tool retention and reliable coolant delivery. Sized for a 16 mm collet bore, it’s ideal for engineers, machinists, and workshop environments that require consistent performance under demanding cutting conditions.

With run-out under 10 microns, a 120 bar high-pressure coolant capability, and a clamping range of 3–20 mm, this collet maintains precise tool alignment while delivering effective cooling and chip evacuation. Newer versions feature a rubber-free nose seal, and the slot geometry is engineered so the longitudinal cuts do not overlap at the center, reducing coolant leakage even under heavy flow.

• Ultra-Precise Run-Out: Delivers sub-10 μm run-out for repeatable positioning and superior surface finish, helping you hit tight tolerances consistently.
• High-Pressure Coolant Capability: Sealed interface supports coolant pressures up to 120 bar, improving chip evacuation and tool life across a 3–20 mm clamping range.
• Leak-Resistant Nose Design: Non-overlapping longitudinal slots prevent coolant loss and, in newer versions, the nose seal is rubber-free to reduce maintenance. For best sealing performance, use only round shank tooling with no clamping flats.

With this ER32 collet, you gain precise toolholding, reliable cooling, and a durable seal that lowers maintenance and downtime. The combination of ultra-low run-out and robust design helps you achieve consistent tolerances, cleaner finishes, and longer tool life, even in demanding milling and drilling tasks. The broad 3–20 mm clamping range and 16 mm size simplify tool changes and reduce setup time, helping your shop run more efficiently.
