The BT40 Shrink Fit Chuck with Front Face Coolant from Omega Products is a precision toolholder built for high-speed CNC work. With a 12 mm shank and a 120 mm length, it delivers secure, repeatable tool mounting on BT40 machines, helping you maintain tight tolerances across demanding milling and drilling tasks.

Compliant with BT MAS403 (JIS 6339) standards and Form AD/B, this chuck includes integrated front coolant channels that direct coolant right to the cutting edge. That efficient cooling supports higher speeds and tougher materials, helping to extend tool life and maintain consistent performance at the spindle speed you rely on—up to 25,000 RPM.

• Integrated front-face coolant channels: Delivers coolant directly to the cutting zone, reducing heat build-up, preserving tool geometry, and enabling more consistent finishes at high speeds.
• BT40 shrink-fit interface with Form AD/B compatibility: Provides secure, repeatable clamping that meets BT MAS403 (JIS 6339) standards, enabling fast tool changes and reliable performance in busy production environments.
• Optimized 4.5-degree engagement, balanced to G2.5 at 25,000 RPM: Ensures smooth, stable cutting with minimal runout and vibration, delivering precise results even during demanding, high-speed operations.

This chucks’ combination of robust clamping, effective cooling, and precise high-speed balance translates into tangible benefits: quicker setups, fewer reworks, cooler tools during long runs, and longer tool life. It’s a dependable, industrial-grade solution designed to keep workflows flowing and finishes consistent across a wide range of materials and applications.
