Omega BT40 Shrink Fit Chucks with Front Face Coolant are engineered to deliver secure tool retention, exceptional rigidity, and dependable performance on BT40 spindles. Perfect for precision milling in job shops, contract manufacturers, and production floors, they help you achieve accurate tool seating with minimal runout even at high speeds.

Built to the BT MAS403 (JIS 6339) standard with Form AD/B geometry and integrated front coolant channels, these chucks actively cool the cutting zone during demanding high-speed operations. Balanced to G2.5 at 25,000 RPM, they provide reliable performance and long-term durability across challenging machining tasks.

• High clamping strength and rigidity: Secure retention and reduced runout for accurate, repeatable machining at high speeds.
• Front-face coolant channels: Efficient cooling directly at the cutting edge to extend tool life, stabilize accuracy, and minimize thermal distortion.
• BT40 Form AD/B compliance and precision balance: Ensures seamless compatibility with BT40 spindles and smooth operation with precise balance (G2.5 at 25,000 RPM).

This shrink-fit chuck solution helps you reduce downtime, improve part consistency, and maintain performance across long production runs. With reliable clamping, integrated cooling, and standards-compliant design, you can trust it to support your most demanding machining workloads from setup through final finish.
