The Omega BT40 Slim Shrink Fit Chuck is a precision toolholding solution for high-speed CNC machining. Its compact, slim profile improves accessibility in tight setups, enabling quicker tool changes and safer operation.

Manufactured to BT MAS403 (JIS 6339) standards, this chuck delivers strong, repeatable clamping with a 3-degree taper and Form AD/B. Balanced to G2.5 @ 25,000 RPM, it offers stable performance and minimal runout for demanding, high-speed applications. It features a 16 mm clamping diameter and a 160 mm gauge length to fit a wide range of machines.

• Slim, accessible design: The compact form reduces interference and makes it easier to reach tooling in crowded spindles, speeding up setup and changeovers.
• Precise, high-strength clamping: BT MAS403 (JIS 6339) compliant construction delivers secure, repeatable grip with robust rigidity across cycles and materials.
• High-speed stability at 25,000 RPM: 3-degree taper with Form AD/B and G2.5 balance minimize runout and vibration for dependable performance at top speeds.

By combining a compact design with proven precision and high-speed stability, this chuck helps you achieve consistent results, smoother finishes, and reliable performance on demanding jobs. The slim profile enhances access in tight setups, while strict standard compliance and precise balancing support repeatable, confident machining every shift.
