Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -17mm

Omega Products ER32 Collet Coolant Sealed, Standard Precision, 17 mm size. This ER32 collet is designed for CNC milling and drilling with coolant systems, delivering a secure grip on round-shank cutters across a 3–20 mm clamping range. It’s a versatile choice for engineers, machinists, hobbyists, and workshops that require precise toolholding and effective coolant containment.

With a run-out specification of less than 10 microns, this collet helps maintain tight tolerances and consistently smooth finishes. The coolant-sealed design reduces leaks and coolant loss, and the newer versions have no rubber seal on the nose to simplify maintenance. For best performance, use solely round-shank tooling with no clamping flats to complete the seal—tool shanks with flats will render the seal ineffective.

• Ultra-precise run-out (<10 μm): Keeps cutter alignment tight for repeatable tolerances and finished surfaces across parts.
• Coolant-sealed design with non-overlapping slots: Prevents coolant loss by preventing seal interference at the center; newer versions remove the nose rubber seal to reduce wear; ensure you use only round-shank tooling with no clamping flats to maintain the seal.
• Wide 3–20 mm clamping range for versatility: Handles a broad range of cutters with a secure grip on round shanks, enabling fast tool changes and reliable performance.

Together, these features deliver a dependable, precise toolholding solution that improves accuracy, reduces rework, and streamlines workflows from setup to finished part. The combination of tight run-out, effective coolant containment, and versatile clamping range gives you confidence to tackle demanding milling and drilling tasks with consistent results.
