Omega Products BT40 Shrink Fit Chucks with Front Face Coolant are built for high-speed BT40 machining, delivering strong clamping and rigidity through shrink-fit technology. Integrated front coolant channels help keep tools cool during aggressive cuts, supporting longer tool life and more consistent results.

Designed to meet BT MAS403 (JIS 6339) standards in the Form AD/B family, these chucks pair a precise 4.5-degree angle with a balanced performance at high speeds. Balanced to G2.5 at 25,000 RPM, they deliver stable, reliable operation even under demanding cutting conditions.

• Front Face Coolant Channels: Integrated coolant paths direct cooling to the cutting edge, reducing heat build-up, maintaining accuracy, and extending tool life during high-speed milling.
• High-Speed Balance at 25,000 RPM: Precision balance (G2.5) minimizes vibration and chatter, delivering smoother finishes and repeatable results across multiple passes and tools.
• BT40 Shrink Fit with Form AD/B & BT MAS403 Compliance: Secure toolholding with standardized interchangeability, easy setup, and reliable performance with compliant BT tooling and spindles.

This combination of robust clamping, efficient cooling, and strict standard compliance helps your workflow run more smoothly, reduces downtime, and delivers consistent machining quality across jobs. Trustworthy construction and proven stability mean you can rely on repeatable results from job to job, time after time.
