Omega Products HSK63A Shrink Fit Chuck - G2.5 - 25,000 RPM - 3mm - 120mm Long

The Omega HSK63A Shrink Fit Chuck is a precision tool-holding solution designed for HSK63A spindles. With a 120 mm length and the ability to grip tool shanks from 3 mm to 32 mm, it delivers secure, repeatable clamping and robust rigidity for demanding milling and high-speed machining.

Using a controlled heating and cooling process, the chuck expands to accept the tool shank and then clamps with a strong, even grip—eliminating tool slip and boosting cutting performance. The G2.5 interface ensures precise tool positioning and accuracy, while a maximum speed of 25,000 RPM makes it ideal for high-speed operations.

• Uniform, high-strength clamping across 3–32 mm shanks: Shrink-fit technology provides an even, secure grip that minimizes tool slippage and extends tool life for reliable performance in every job.
• Precise, repeatable positioning with G2.5 interface: Ensures accurate tool alignment on each change, reducing runout and delivering consistent cuts across multiple setups.
• High-speed performance up to 25,000 RPM: Designed for fast, efficient machining with HSK63A spindles while maintaining a secure grip and dependable reliability at high speeds.

With the Omega HSK63A Shrink Fit Chuck, you’ll experience faster, more confident tool changes, improved rigidity, and consistent results across projects. Its durable construction and high-speed capability help streamline setups, minimize downtime, and elevate overall machining performance in both production and workshop environments.
