Omega Products HSK63A Shrink Fit Chuck - G2.5 - 25,000 RPM - 14mm - 90mm Long

The Omega Products HSK63A Shrink Fit Chuck is a precision toolholding solution designed for high-speed machining on HSK63A spindles. It securely clamps tool shanks from 3 mm to 32 mm, delivering a consistent, rigid grip that minimizes slippage and enhances cutting performance at speeds up to 25,000 RPM.

• Uniform, High-Pressure Clamping: The shrink-fit process expands the chuck with controlled heating and then contracts around the tool shank to provide an even, strong grip that eliminates slip and maximizes rigidity for longer tool life and steadier cuts.
• High-Speed Precision with G2.5 Interface: The G2.5 interface delivers precise tool positioning and repeatable accuracy at up to 25,000 RPM, helping maintain tight tolerances and a consistent finish across demanding jobs.
• Wide Shank Range and Durable Construction: Designed to accommodate 3–32 mm shanks and built for repeated high-speed use on HSK63A spindles, offering reliable retention and long service life in busy production environments.

This shrink-fit chuck enables confident, repeatable toolholding that supports stable toolpaths, cleaner finishes, and extended tool life. With fast, controlled expansion and secure contraction, setup is straightforward and tool changes are reliable, helping you keep productivity high and results consistent across applications.
