The Omega HSK63A Shrink Fit Chuck securely grips cutting tools with shanks from 3 mm to 32 mm and is compatible with HSK63A spindles. Through a controlled heating and cooling process, the chuck expands uniformly to accept the tool shank, then clamps with a strong, even grip. This eliminates tool slippage and provides maximum rigidity, boosting tool life and cutting performance.

The G2.5 interface delivers precise tool positioning and repeatable accuracy, while the 25,000 RPM maximum speed rating makes this chuck ideal for high-speed machining applications.

• Broad shank compatibility (3–32 mm): Securely holds a wide range of tool shanks and works with HSK63A spindles, reducing the need for multiple chucks and simplifying setups.
• Uniform, high-precision shrink clamping: Heating and cooling expand the chuck evenly, then apply a consistent clamping force for minimal slip and maximum rigidity, extending tool life and ensuring stable cuts.
• High-speed precision and reliability: G2.5 interface provides exact tool positioning at up to 25,000 RPM, enabling clean finishes and dependable performance in demanding environments.

This shrink-fit chuck helps streamline your workflow by enabling fast, repeatable tool changes, locking tools securely for vibration-free operation, and delivering consistent results across a range of high-speed applications. With its broad compatibility, precise positioning, and rugged reliability, it supports improved productivity and higher-quality finishes in daily machining work.
