The Omega BT50 Shrink Fit Chuck is a precision tool-holding solution designed for high-speed milling and drilling. Engineered for BT50 spindle systems, it uses a heat-expanded shrink-fit to securely grip tool shanks, delivering outstanding concentricity and stability up to 25,000 RPM. This makes it a reliable choice for engineers, machinists, and workshop professionals who demand repeatable accuracy in demanding tasks.

With a G2.5 precision rating, this chuck minimizes runout for consistent results across passes, while its 100 mm overall length and 4 mm tool shank compatibility provide a compact, easy-to-integrate setup for a wide range of tooling needs. The shrink-fit design also delivers excellent vibration damping, helping maintain surface finish and reducing tool deflection during cuts.

• Precise concentricity with G2.5 rating: Ensures minimal runout for accurate, repeatable results at high speeds, improving both roughing and finishing passes.
• High-speed capability up to 25,000 RPM: Supports demanding milling tasks with stable grip and reliable cutting action even at elevated feed rates.
• Secure shrink-fit mechanism with heat expansion: Firmly grips 4 mm tool shanks for reduced vibration and deflection, delivering smoother finishes and longer tool life.

This combination of precision, durability, and straightforward setup helps you streamline your workflow. Expect consistent tool retention, reduced downtime from slips, and higher-quality finishes across a range of materials—whether you're prototyping, performing precision machining, or running higher-volume production.
