The Omega BT40 ER Collet Chuck is a precision tool holder designed for BT40 spindles, built to securely clamp ER40 tooling for stable, repeatable milling and drilling performance.

• BT40 compatibility: Specifically engineered for BT40 spindle systems, ensuring secure mounting and reliable alignment.
• ER40 collet system: Uses standard ER40 tooling to support a wide range of cutting tools with dependable clamping.
• High-speed capability: Rated for operational speeds up to 25,000 RPM for efficient machining and consistent results.
• Precision you can trust: G2.5 and G6.3 precision ratings indicate excellent tool concentricity with minimal runout.
• Gauge length: 160 mm gauge length designed to provide a balanced combination of rigidity and reach for longer tool paths.
• Form AD/B design: Form AD/B configuration tailored for BT40 spindles, promoting secure, repeatable tool clamping.

With its ER40 collet system and tight tolerances, this chuck delivers excellent concentricity and minimal runout, translating to improved surface finish and consistent dimensional accuracy across parts. The 160 mm gauge length offers a stable interface for longer tooling paths, reducing deflection and chatter at high RPMs. Designed for metalworking shops and job shops performing precision milling and drilling, the Omega BT40 ER Collet Chuck supports a wide range of tools and operations, from light finishing passes to demanding pocketing tasks, all while maintaining repeatable performance.
