Omega Products ER32 Collet Coolant Sealed Standard Precision - 10 Micron Run-Out -19mm

Omega Products ER32 Collet Coolant Sealed Standard Precision is a precision ER32 collet designed for CNC milling and drilling where coolant management and tight run-out control are critical. It securely clamps round shank tooling in a 3–20 mm range, delivering run-out of less than 10 μm for repeatable, high-quality finishes.

Newer versions feature a simplified nose design with no rubber seal, while the core seal relies on non-overlapping longitudinal slots to minimize coolant loss. For best results, use only round shank tooling with no clamping flats to ensure the seal remains effective.

• Ultra-low run-out (≤10 μm): Ensures consistent accuracy across multiple passes, reducing part deviation and improving surface finish.
• Reliable coolant sealing design: Non-overlapping slots at the center prevent coolant leakage, keeping chips and coolant where they belong for cleaner machining operations.
• Wide clamping range for round tooling (3–20 mm): Lets you use a broad selection of tools without swapping hardware, plus clear guidance to use round shanks without clamping flats for optimal performance.

This collet system supports efficient, dependable milling and drilling with cleaner coolant control and repeatable results. Its robust construction and precise clamping help minimize downtime, improve productivity, and deliver consistent performance across a range of materials and applications—from maker benches to production environments.
