Omega Products HSK63A Face Mill Arbor - Through Coolant - G2.5 - 25,000RPM - 32mm Spigot - 60mm Gauge Length

The Omega Products HSK63A Face Mill Arbor with Through Coolant is designed for high‑speed milling where rapid heat dissipation and stable tool performance are critical. It features a precision HSK63A shank for maximum rigidity and accuracy, paired with a G2.5 through-coolant system that delivers coolant directly to the cutting edge for cooler tools, cleaner chips, and longer tool life.

This arbor fits face mills with bore diameters from 16 mm to 32 mm and is optimized for spindle speeds up to 25,000 RPM. It has a 32 mm spigot and a 60 mm gauge length to ensure a secure, repeatable fit in demanding production environments.

• Rigid HSK63A interface: Maximizes rigidity and accuracy at high speeds, reducing runout and improving surface finish even with demanding milling applications.
• Direct through-coolant delivery (G2.5): Delivers coolant right to the cutting edge, extending tool life, enhancing chip evacuation, and allowing higher-performance milling without overheating.
• Wide bore compatibility with secure seating: Supports face mills from 16–32 mm bore, with a 32 mm spigot and 60 mm gauge length to ensure stable, repeatable alignment and quick setup.

This arbor helps you increase throughput and consistency across jobs by combining rigid seating, efficient cooling, and versatile bore compatibility. The through-coolant design reduces heat in both tool and workpiece, while the robust HSK63A interface minimizes deflection during aggressive milling. With its precise fit and high RPM capability, you can achieve repeatable results, reduce downtime, and simplify tool changes in busy shops.
