Omega Products BT40 Shrink Fit Chucks with Front Face Coolant - G2.5 - 25,000RPM - 14mm - 160mm

Omega BT40 Shrink Fit Chuck with Front Face Coolant is built to deliver secure, repeatable toolholding for BT40 milling applications. Designed for engineers, machinists, and workshops that demand reliable clamping and rigid performance, this chuck helps maintain accuracy and reduce runout during demanding cuts. It’s engineered to work with high-speed machining setups while keeping the tool cool and stable.

Ideal for high-speed work, this shrink-fit chuck integrates front coolant channels to efficiently remove heat at the cutting edge, helping extend tool life and maintain dimensional stability even under continuous operation. The Form AD/B configuration and BT MAS403 (JIS 6339) standard compliance ensure dependable compatibility and consistent performance across compatible machines.

• Strong, repeatable clamping: Shrink-fit design delivers uniform, high clamping force for minimal tool deflection and consistent part accuracy across long machining runs.
• Front-face coolant for efficient cooling: Integrated coolant channels actively remove heat at the cutting edge, reducing thermal expansion and preserving tool life during high-speed operations.
• Precision and reliability at speed: Precisely engineered with a 4.5-degree seating angle and balanced to G2.5 at 25,000 RPM, while conforming to BT MAS403 (JIS 6339) standards for smooth, dependable performance.

This BT40 Shrink Fit Chuck with Front Face Coolant is a practical, high-precision solution for demanding milling tasks. By combining robust clamping, effective cooling, and careful balance at high RPMs, it supports faster setups, reduces downtime, and helps you achieve cleaner finishes with each job.
