Omega BT40 Shrink Fit Chuck with G2.5 precision is engineered for high-speed machining where accuracy and reliability matter. Specifically designed for BT40 spindles and 8 mm tooling, its 90 mm long body provides versatile reach for a wide range of parts, while maintaining a secure, consistent grip at up to 25,000 RPM.
Its shrink-fit design uses heat expansion to firmly clamp the tool shank, delivering exceptional stability and vibration damping. This reduces tool deflection, minimizes runout, and helps achieve smoother surface finishes even on tough materials.
- G2.5 precision with minimal runout: Delivers exceptional concentricity for accurate tool paths and repeatable results, even at high speeds.
- Secure heat-shrink clamping: Heat-activated grip around the 8 mm tool shank provides stable cutting action, lower vibration, and longer tool life.
- High-speed performance for BT40: Ready for demanding milling tasks up to 25,000 RPM with a 90 mm long body and 8 mm shank, offering versatile use across materials.
This BT40 shrink-fit chuck helps you streamline setups, reduce downtime, and achieve consistent, repeatable results across a wide range of projects. The combination of tight concentricity, vibration damping, and robust clamping means better surface finishes, less tool wear, and improved overall productivity on both simple and complex parts.
