Omega Products HSK63F ER Collet Chucks are precision toolholders engineered for high-speed milling and drilling. With a rigid HSK63F shank and ER16 compatibility, they deliver exceptional rigidity and accuracy, keeping runout to a minimum even at speeds up to 25,000 RPM. The 70mm gauge length provides a compact, stable interface that helps reduce overhang and vibration in tight setups. Rigid HSK63F shank for stable, accurate toolholding: The high-rigidity interface minimizes deflection and chatter, improving cutting accuracy and extending tool life across demanding materials. Precise G2.5 runout for consistent cutting: Low runout reduces vibration and improves surface finish, enabling tighter tolerances and more reliable results at high speeds. ER16 clamping versatility for a wide tool range: The ER16 system allows clamping a broad range of tool diameters, enabling quick tool changes with maintained grip and accuracy. Designed for reliability in demanding environments, this chuck enhances productivity with stable toolholding at high RPM, reducing rework and downtime. Its precise runout and versatile ER16 collets enable finer finishes and longer tool life, making it a dependable choice for professional shops and serious hobbyists tackling high-speed machining tasks.
