Omega’s BT40 Shrink Fit Chuck with Front Face Coolant is designed for precision milling, delivering secure tool retention and enhanced rigidity to help maintain tight tolerances in demanding workpieces.

Compliant with BT MAS403 (JIS 6339) standards, it features Form AD/B with integrated front coolant channels for efficient cooling during high-speed operations. With a precise 4.5-degree angle and balance grade G2.5 at 25,000 RPM, it delivers reliable, smooth performance across challenging machining tasks.

• Strong, precise clamping: Secure tool retention and rigidity reduce runout, improving part accuracy and extending tool life.
• Integrated front-face coolant: Efficient cooling at the cutting edge minimizes heat buildup, preserves dimensions, and supports longer, more consistent tool performance in high-speed work.
• BT40 compatibility and precise balance: Form AD/B compliance with a 4.5-degree engagement and G2.5 balance at 25,000 RPM for dependable, smooth operation in demanding environments.

This combination helps you improve workflow and reliability: faster cycles, less downtime, and more consistent results across a range of materials. Built to endure demanding shop conditions, the chuck delivers steady performance and long service life, giving you confidence in every cut.
