The Omega BT40 ER Collet Chuck is a precision tool holder built for BT40 spindle systems and ER16 tooling. It delivers secure tool clamping, high-speed stability, and repeatable accuracy for demanding milling operations.

• BT40 spindle compatibility: Specifically designed to fit BT40 milling centers for reliable mounting and consistent performance.
• ER16 tool interface: Accepts standard ER16 collets, enabling a wide range of cutting tools and configurations.
• Operational speed: 15,000–25,000 RPM, supporting fast material removal across a variety of materials and applications.
• Gauge length: 160 mm gauge length contributes to rigidity and predictable tool geometry during heavy machining.
• Precision ratings: G2.5 precision (with G6.3 noted in related specifications) for tight concentricity and minimal runout, improving finish and cut quality.
• Form: Form AD/B design aligns with standard BT40 tooling interfaces for secure engagement and reliable clamping.
• Construction quality: Precision-machined components deliver stable toolholding and durable performance under high-speed operation.

This chuck is ideal for professionals performing high-speed milling where tool rigidity and concentricity directly influence surface finish and dimensional accuracy. Use it with ER16 tooling for a versatile range of end mills, drills, and inserts, benefiting applications from aluminum prototyping to precision steel components. Its combination of a generous 160 mm gauge length, robust clamping, and high RPM capability helps reduce tool chatter, maintain tight tolerances, and shorten cycle times across multiple setups.
