The BT40 Shrink Fit Chuck with Front Face Coolant from Omega is engineered for high-speed milling on BT40 spindles. It delivers a secure, uniform grip on cutting tools through shrink-fit clamping, minimizing runout and enhancing overall accuracy for demanding machining tasks.

Integrated front-face coolant channels actively cool the tool during operation, helping reduce heat buildup, extend tool life, and improve surface finish at high speeds. Built to BT MAS403 (JIS 6339) standards with Form AD/B, this chuck offers proven reliability in busy production environments. It is balanced to G2.5 at 25,000 RPM and features a precise 4.5-degree seating angle for stable, vibration-free performance.

• Secure shrink‑fit clamping: Delivers a strong, uniform grip with minimal runout, improving accuracy and extending tool life in high-speed milling.
• Front‑face coolant cooling: Directs coolant to the cutting edge, reducing heat, preserving tool geometry, and delivering cleaner finishes.
• BT40 standard with precise balance: Meets BT MAS403 (JIS 6339) Form AD/B and is balanced to G2.5 at 25,000 RPM for reliable, smooth operation.

This combination translates to faster setups, fewer tool changes, and consistent results across a range of materials. It supports your workflow with stable performance at high speeds, improved surface quality, and dependable operation—giving you confidence to push productivity without compromising precision.
