The Omega HSK63A Shrink Fit Chuck is a precision tool holder designed for HSK63A spindles. It securely grips tool shanks from 3 mm to 32 mm using a controlled heat-and-cool shrink-fit process, delivering a uniform clamp and maximum rigidity for consistently accurate cuts. Its 160 mm overall length keeps tooling stable and aligned during high-speed machining.

• Uniform, slip-free clamping for extended tool life: The shrink-fit action creates a strong, even grip on shanks (3–32 mm), minimizing tool slip and vibration to protect cutting edges and improve endurance between changes.
• High-speed precision with reliable positioning: The G2.5 interface together with a 25,000 RPM rating ensures precise tool placement and stable performance at high speeds for better surface finish and productivity.
• Fast, repeatable setup with durable construction: Heat-to-expand and cool-to-clamp operation enables quick tool changes and repeatable retention, while robust materials and design deliver long-term reliability in demanding environments.

This shrink-fit chuck helps you optimize setup time, maintain tight runout control, and achieve consistent results across demanding milling tasks. By pairing strong, uniform clamping with high-speed capability, it supports longer tool life and improved cutting performance—whether you’re refining precision parts or pushing material removal in busy production workflows.
