Meet the Omega BT40 Shrink Fit Chuck with Front Face Coolant—designed for BT40 spindle systems and high-speed milling. It delivers strong, repeatable clamping and rigid toolholding, while integrated front-face coolant channels keep the cutting zone cool during demanding cuts. Built to BT MAS403 (JIS 6339) standards and Form AD/B, it’s balanced to G2.5 at 25,000 RPM for smooth, reliable performance.

• Rigid shrink-fit clamping for consistent results: Shrink-fit gripping around the tool shank provides even clamping pressure, reducing runout and delivering repeatable accuracy through long production runs.
• Front-face coolant delivery for efficient cooling: Integrated coolant channels direct cooling fluid to the cutting edge, helping control heat, minimize thermal distortion, and extend tool life during high-speed cuts.
• High-speed precision balance: A precise 4.5-degree seating with G2.5 balance at 25,000 RPM delivers stable cutting, reduced vibration, and reliable surface finishes across challenging materials.

With these capabilities, the BT40 Shrink Fit Chuck enhances workflow by maintaining tight tolerances, reducing downtime, and enabling faster, more consistent cycle times without compromising accuracy or reliability. Built for durability and backed by industry-standard compliance, it provides confidence for production environments, job shops, and demanding machining tasks across a wide range of applications.
