Omega's BT40 Shrink Fit Chuck with Front Face Coolant is engineered for high-speed CNC milling, delivering secure, rigid toolholding for 6 mm tooling with a compact 120 mm form factor. Compliant with BT MAS403 (JIS 6339) standards, this chuck also integrates front coolant channels to keep cutting tools cool and performance stable at speeds up to 25,000 RPM.

• Front Face Coolant Integration: Delivers coolant directly to the cutting zone for efficient heat removal during high-speed milling, helping extend tool life and maintain consistent finish quality.
• Balanced G2.5 at 25,000 RPM: Form AD/B design provides rigid, stable seating with minimal runout, delivering precise, repeatable performance even at high spindle speeds.
• BT40 Interface with BT MAS403 (JIS 6339) Compliance: Ensures reliable fitment with standard spindles, easy tool changes, and interchangeability across compatible equipment for reduced downtime.

By combining direct front-face cooling, precise balance, and a standard BT40 interface, this chuck minimizes downtime, reduces tool heat-related distortion, and delivers repeatable clamping force across batches. Whether you’re producing tight tolerance parts or performing high-speed milling, you can trust this shrink-fit chuck to keep your spindle turning smoothly, your tools cooler, and your parts within spec—shift after shift.
