Omega Products ER32 Collet Coolant Sealed Ultra Precision - 10 Micron Run-Out - 7mm

The Omega ER32 Collet Coolant Sealed Ultra Precision is a high‑performance toolholding solution designed for milling and drilling applications that demand steady coolant delivery and exceptionally tight run‑out. It’s ideal for machine shops, engineers, and professional tradespeople who need reliable clamping, clean chip management, and consistent results across jobs.

Key strengths include a 120 bar high‑pressure coolant capability and a clamping range of 3–20 mm, with a 7 mm model within that range. The newer versions feature an integral metal seal with no rubber seal on the nose, and the longitudinal slots are designed so they do not overlap at the centre, helping prevent coolant loss. For best results, use only round‑shank tooling with no clamping flats, as flats will render the seal ineffective.

• Ultra-precise run-out: Delivers repeatable accuracy (under 10 microns) for consistent tool positioning, better surface finish, and longer tool life.
• High‑pressure coolant seal with integral metal seal: Maintains coolant delivery up to 120 bar and reduces leaks and splash, even under demanding cutting conditions.
• Wide clamping range with round‑shank tooling: Covers 3–20 mm tooling within the ER32 standard; to preserve the seal, use round‑shank tools with no clamping flats—flats will render the seal ineffective.

By choosing this coolant‑sealed ER32 collet, you gain a dependable setup that streamlines workflow, improves cutting efficiency, and delivers consistent results across jobs. The robust design minimizes coolant loss, enhances surface finish, and supports longer tool life, helping you complete tasks faster with fewer adjustments.
