The Omega HSK63A Shrink Fit Chuck is a precision tool holder engineered for HSK63A spindles. It accommodates tool shanks from 3 mm to 32 mm, making it a versatile choice for a wide range of milling tasks in manufacturing, engineering, and hobbyist shops.

Using a controlled heating and cooling cycle, the chuck expands to accept the tool shank and then clamps with a strong, even grip. This shrink-fit method eliminates tool slippage, delivers maximum rigidity, and helps extend tool life while improving overall cutting performance.

• Uniform shrink-fit clamping for maximum rigidity: The precise expansion and uniform gripping along the entire shank prevent slip, delivering consistent accuracy and better surface finishes.
• G2.5 interface for precise tool positioning: Ensures repeatable alignment with the spindle, reducing setup time and improving machining reliability.
• High-speed capability up to 25,000 RPM: Optimized for fast, high‑speed machining applications while maintaining solid retention and improved cutting performance.

This shrink-fit chuck helps you streamline workflows by delivering secure tool retention, reliable performance at high speeds, and longer tool life. With a robust HSK63A fit, it provides dependable, repeatable results across multiple tools, helping you achieve cleaner finishes and higher productivity.
