Omega BT40 Shrink Fit Chuck with G2.5 precision is a dedicated toolholding solution for high‑speed milling on BT40 spindles. It securely grips 6 mm tool shanks using heat expansion, delivering excellent concentricity and stability up to 25,000 RPM. The 90 mm long body is designed for compatibility with a wide range of machines, giving you reliable performance in busy shops and precision-focused projects.

• G2.5 precision with minimal runout: Ensures tight concentricity on 6 mm tool shanks for accurate, repeatable cuts across every pass.
• High-speed performance up to 25,000 RPM: Maintains grip and balance at top speeds, reducing tool deflection and delivering smoother finishes.
• 90 mm long shrink-fit body for stable mounting: Heat-expanded grip provides strong, vibration-damping clamping that stays centered under load.

Together, these features translate into steadier tool performance, tighter tolerances, and more consistent finishes across demanding milling tasks. The heat-expanded shrink-fit grip locks the 6 mm tool shank securely, reducing vibration and deflection even at full speed, while the compact 90 mm body integrates smoothly into BT40 spindles. In daily production, you’ll benefit from reliable setup, repeatable results, and the confidence to push feeds and speeds with less rework.
