Omega BT40 Shrink Fit Chuck with Front Face Coolant is a precision toolholding solution designed for BT40 milling spindles. Built for high-speed machining, it delivers strong clamping force and rigid tool retention, with integrated front-face coolant channels to keep the cutting zone cool during demanding operations.

Compliant with BT MAS403 (JIS 6339) standards and featuring Form AD/B geometry, this chuck is sized for a 32 mm interface and an overall length of 160 mm. It’s balanced to G2.5 at 25,000 RPM and includes a precise 4.5-degree angle to support stable cutting and reliable performance at speed.

• Front Face Coolant Integration: Integrated coolant channels deliver cooling directly to the tool and cutting zone, helping maintain precision, reduce thermal distortion, and extend tool life during high-speed milling.
• Shrink-Fit BT40 with Form AD/B: Uniform clamping around the tool shank provides high rigidity and repeatable retention, minimizing runout and improving surface finish across demanding applications.
• High-Speed Balance and Precision: Balanced to G2.5 at 25,000 RPM with a 4.5-degree contact angle, delivering smooth operation, reduced vibration, and consistent cutting performance at top speeds.

Together, these features translate to a dependable, high-performance chuck that supports longer tool life, better finishes, and faster cycle times. The front-face coolant and robust shrink-fit design ensure reliable cooling and secure retention, while BT MAS403 (JIS 6339) compliance and precise balancing provide confidence for both daily production and precision work.
