Omega Products HSK63A Shrink Fit Chuck - G2.5 - 25,000 RPM - 25mm - 115mm Long

The Omega HSK63A Shrink Fit Chuck is a high-precision tool holder engineered for HSK63A spindles. It securely grips tool shanks from 3 mm to 32 mm and comes in a compact 115 mm length to fit a wide range of machines. The shrink-fit process provides quick, uniform expansion for tool insertion and a strong, evenly distributed clamping force, delivering maximum rigidity and improved cutting performance at speeds up to 25,000 RPM. The G2.5 interface ensures precise tool positioning and repeatable accuracy for demanding milling and drilling tasks.

• Wide tool-holding range (3–32 mm): Supports a broad spectrum of cutting-tool shanks, enabling quick swaps without hardware changes and reducing downtime, while maintaining secure, uniform grip for consistent performance.
• Uniform shrink-fit clamping for maximum rigidity: The heating and cooling process expands the chuck evenly, then clamps the tool shank with a strong, even grip. This minimizes tool slip and delivers stable cutting performance and longer tool life.
• G2.5 interface with 25,000 RPM capability: Delivers precise tool positioning and accurate alignment with HSK63A spindles while handling high-speed machining to maintain surface finish and dimensional accuracy.

With secure retention, repeatable accuracy, and high-speed capability, this shrink-fit chuck helps you maintain tight tolerances, achieve cleaner finishes, and reduce tool changes. It supports efficient workflows in shops, production lines, and hobby setups alike, delivering reliable performance when it matters most.
