Omega BT40 Shrink Fit Chuck with Front Face Coolant is a precision tool holder designed for BT40 spindles. It delivers strong clamping and rigidity for high-speed milling, helping you maintain accuracy and finish even at top speeds. The integrated front-face coolant channels ensure efficient cooling during demanding operations, reducing heat build-up and extending tool life.

Compliant with BT MAS403 (JIS 6339) standards, the Form AD/B construction provides secure seating and repeatable performance. The chuck is precisely balanced to G2.5 at 25,000 RPM, offering smooth, vibration-free operation. Optimized for 8 mm tooling and with an overall length of 160 mm, it delivers reliable reach and compatibility for a wide range of CNC configurations.

• Integrated front-face coolant channels: Efficient cooling during high-speed machining keeps tools cooler, reduces thermal distortion, and extends tool life for consistent results.
• BT40 with Form AD/B, BT MAS403 compliance: Ensures secure tool seating, repeatable clamping force, and reliable performance in demanding applications.
• Balanced at G2.5 @ 25,000 RPM with 8 mm tooling and 160 mm length: Delivers smooth operation, minimal vibration, and stable accuracy across fast-spindle milling setups.

Designed to streamline your workflow, this shrink-fit chuck helps reduce setup time and downtime while delivering reliable clamping and consistent results at high speeds. Its front-coolant design manages heat effectively, supporting longer tool life and better surface finishes, so you can trust it in precision milling, die work, and intricate components.
