Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -4mm

Omega's ER32 Collet with coolant seal is a reliable tool holder designed for milling, drilling, and precision machining. It supports a broad clamping range (3–20 mm) and helps deliver consistent, repeatable cuts with tight run-out for smooth finishes across jobs.

The collet achieves standard precision with run-out under 10 microns. Some newer versions omit the rubber seal on the nose, and the longitudinal slots are arranged so they do not overlap at the center, which helps prevent coolant loss. For best performance, use only round shank tooling with no clamping flats; tooling with flats will render the seal ineffective.

• Ultra-precise run-out (<10 μm): Delivers repeatable, accurate toolholding for cleaner cuts, better tolerances, and reduced rework.
• Coolant-sealed nose with non-overlapping slots: Minimizes coolant leakage and keeps coolant and chips where they belong, improving cleanliness and tool life. To maintain the seal, use only round shank tooling with no clamping flats.
• Wide clamping range (3–20 mm) with durable construction: Accepts a broad set of standard tools and holds them securely for reliable performance across demanding milling and drilling tasks.

This coolant-sealed ER32 collet is built to support efficient workflows, helping you maintain consistent results, reduce downtime, and protect your spindle setup. Its simple, robust design provides dependable grip and precision across a wide range of tools, making it a solid choice for shop floors, job shops, and home workshops alike.
