Omega Products BT40 Shrink Fit Chucks with Front Face Coolant - G2.5 - 25,000RPM - 5mm - 160mm

The Omega BT40 Shrink Fit Chuck with Front Face Coolant is a precision toolholding solution for BT40 spindle systems, delivering strong clamping and repeatable accuracy in demanding milling environments.

Designed to accommodate 5 mm tool shanks and a 160 mm length profile, it conforms to BT MAS403 (JIS 6339) Form AD/B standards and includes integrated front-face coolant channels for efficient cooling during high-speed work up to 25,000 RPM.

• Integrated Front Face Coolant: Delivers coolant directly to the cutting edge during high-speed milling, reducing heat buildup and helping maintain accuracy and tool life.
• Form AD/B BT40 Shrink Fit with BT MAS403 Compliance: Provides strong, repeatable clamping and rigidity with standard compatibility, ensuring reliable performance across setups and shops.
• Balanced to G2.5 @ 25,000 RPM with 4.5° Interface: Ensures stable, low-vibration operation at high speeds and precise tool seating for consistent finishes and repeatable results.

With these design features, the chuck helps you streamline tool changes, improve surface finish, and reduce downtime in high-speed machining. The front-face coolant keeps temperatures predictable, the shrink-fit clamp delivers consistent runout control, and the BT MAS403/Form AD/B compatibility simplifies exchanges across equipment, making it a dependable choice for engineers, machinists, and job shops operating at up to 25,000 RPM.
