Omega BT40 Shrink Fit Chuck with Front Face Coolant is a precision toolholding solution designed for BT40 spindle systems. It delivers strong, repeatable clamping and rigidity for demanding milling and drilling tasks, making it a reliable choice for engineers, machinists, and shop teams that operate at speed.

Featuring integrated front-face coolant channels, compliant with BT MAS403 (JIS 6339) Form AD/B, and balanced to G2.5 at 25,000 RPM, this chuck maintains cutting performance under aggressive feeds and high temperatures. The precise 4.5-degree engagement angle helps ensure consistent tool seating and long-term reliability.

• Front Face Coolant Integration: Directs coolant through the chuck’s front face to the cutting zone, keeping temps down, reducing thermal growth, and helping sustain tight tolerances during high-speed machining.
• BT MAS403/JIS 6339 Form AD/B Compliance: Ensures reliable BT40 compatibility with standardized form factors, enabling secure seating and easy interchange with compatible machines.
• High-Speed Precision and Balance: Precisely balanced to G2.5 at 25,000 RPM with a 4.5-degree engagement angle for smooth operation, reduced vibration, and longer tool life under heavy cutting.

With the Omega BT40 Shrink Fit Chuck, you gain faster tool changes, consistent clamping, and effective cooling across a wide range of BT40 applications. The combination of front-face coolant, standard-compliant form, and meticulous balance supports better surface finishes, tighter tolerances, and higher overall productivity in your machining workflow.
