Omega BT40 Shrink Fit Chuck is a precision tool-holding solution designed for high-speed CNC milling and drilling. Built for BT40 spindles, its 120 mm length provides sturdy guidance and versatile reach for a wide range of setups, making it suitable for engineers, machinists, hobbyists, and production shops alike. With a G2.5 precision rating, this chuck delivers true tool alignment and repeatable results, even at demanding speeds.

• G2.5 Precision Concentricity: Excellent tool concentricity and minimal runout ensure accurate, repeatable cuts and smoother finishes across long programs.
• High‑Speed Capability up to 25,000 RPM: Designed for demanding tasks, it maintains stable performance with reduced vibration, enabling faster material removal without sacrificing accuracy.
• Shrink‑Fit Retention for 4 mm Shanks: Heat-expanded grip provides a secure, vibration-damped hold on small-diameter shanks, reducing deflection and improving surface quality.

This BT40 Shrink Fit Chuck helps streamline your workflow by delivering reliable tool retention, precise alignment, and durable performance in everyday milling and finishing tasks. The combination of high-speed capability, tight concentricity, and a secure shrink-fit grip translates to fewer reworks, cleaner surfaces, and longer tool life—whether you’re building prototypes, fabricating parts, or performing routine maintenance in a busy workshop.
