Omega Products BT40 Shrink Fit Chucks with Front Face Coolant are built for BT40 milling centers, delivering a secure, rigid tool grip during high-speed operations. The shrink-fit design transfers clamping force directly to the tool shank, minimizing runout and improving concentricity for better part tolerances. With integrated front-face coolant channels, coolant flows directly to the cutting edge, helping manage heat and extend tool life during demanding cuts.

These chucks comply with BT MAS403 (JIS 6339) standards and feature Form AD/B, a precise 4.5-degree relief angle, and balanced performance at 25,000 RPM. This combination ensures reliable operation, reduced vibration, and consistent results across a range of materials and applications.

• Powerful shrink-fit clamping: Delivers a tight, repeatable grip on tool shanks to minimize runout and maintain tight tolerances at high speeds.
• Front-face coolant channels: Provides direct cooling to the cutting edge for better heat management, longer tool life, and cleaner finishes during high-speed machining.
• BT MAS403 compliant with precise balance: Meets industry standards (JIS 6339) with Form AD/B, a 4.5-degree angle, and G2.5 balance at 25,000 RPM for stable, reliable performance.

Designed for professionals across engineering, manufacturing, and workshop environments, this BT40 shrink-fit chuck helps you maintain consistent results, reduce downtime, and achieve better surface finishes. With robust construction, integrated coolant cooling, and industry-standard compatibility, you can rely on it for demanding milling and drilling tasks.
