Omega Products BT40 Shrink Fit Chuck with G2.5 precision is a secure, high-precision tool-holding solution built for high-speed machining. It delivers excellent tool concentricity and minimal runout, ensuring accurate and repeatable results. Designed for 12 mm shanks and 120 mm overall length, it operates up to 25,000 RPM to tackle demanding milling and drilling tasks with confidence.

The shrink-fit design uses controlled heat expansion to firmly grip the tool shank, delivering stability, vibration damping, and reduced deflection. This means smoother finishes, longer tool life, and fewer interruptions during production.

• G2.5 Precision Concentricity: Delivers tight concentricity and minimal runout for accurate, repeatable toolpaths at high speeds, improving surface finish and dimensional accuracy.
• High-Speed Performance up to 25,000 RPM: Maintains stability under demanding feeds, reduces chatter, and enables consistent results in tough milling and drilling tasks.
• Shrink-Fit, 12 mm Shank / 120 mm Length: Heat-expanded grip provides a secure, vibration-damped hold and quick tool changes, helping reduce downtime and extend tool life.

With these capabilities, you gain dependable tool retention, faster changeovers, and more consistent results across jobs. The combination of precision concentricity, high-speed stability, and shrink-fit clamping helps you improve surface finish, reduce rework, and keep your workflow moving smoothly.
