Omega's BT40 Shrink Fit Chuck with Front Face Coolant is built for BT40 milling setups, supporting 6 mm tool shanks within a compact 90 mm body. It delivers a rigid, repeatable grip with integrated front-face coolant channels for effective cooling during high-speed cutting, and is balanced to G2.5 at 25,000 RPM while conforming to BT MAS403 (JIS 6339) Form AD/B standards.

• Front-face coolant integration: Direct cooling at the cutting edge reduces thermal distortion, promotes consistent tool life, and helps maintain accuracy at high speeds up to 25,000 RPM.
• BT40 shrink-fit with Form AD/B compliance: Delivers precise, repeatable tool holding with strong clamping force and full compatibility with standard BT40 tooling.
• High-speed balance and precise seating: 4.5-degree seating angle and G2.5 balance at 25,000 RPM ensure low runout, stable cutting, and smooth finishes across materials.

This chuck supports a reliable machining workflow: secure, repeatable tool holding; effective cooling to extend tool life; and proven precision at high speeds. With 6 mm tooling and a 90 mm body, it offers versatility for deeper pockets and diverse milling tasks while maintaining BT40 compatibility.
