The Omega HSK63A Face Mill Arbor with Through Coolant is a precision tool holder designed for engineers, machinists, and shop floor operators who demand reliable high-speed milling performance. It accepts face mills with bores from 16 mm to 32 mm and features a 32 mm spigot with a 160 mm gauge length, optimized for through-coolant cooling at spindle speeds up to 25,000 RPM. The result is cleaner cuts, cooler tools, and consistent results in demanding milling tasks.

• Through-Coolant Delivery to the Cutting Edge: Direct coolant flow through the arbor keeps the cutting edge cooler, improves chip evacuation, and helps extend tool life during high-speed milling.
• Rigid HSK63A Interface for Precision: A precision HSK63A shank delivers maximum rigidity and repeatable seating, reducing runout and vibrations for smoother cuts and tighter tolerances.
• Broad Bore Compatibility & High-Speed Performance: Supports face mills with 16–32 mm bores and is rated up to 25,000 RPM, enabling versatile setups with fewer tool changes and consistent results across jobs.

Designed for reliable, day-in, day-out milling performance, this arbor stabilizes your tool assembly while delivering efficient cooling and precise alignment. The combination of through-coolant capability, robust HSK63A interface, and wide bore compatibility helps you achieve better surface finishes, longer tool life, and improved workflow productivity with fewer interruptions.
