Omega Products HSK63A Face Mill Arbor - Through Coolant - G2.5 - 25,000RPM - 16mm Spigot - 45mm Gauge Length

The Omega Products HSK63A Face Mill Arbor with Through Coolant is built for high-speed milling applications where reliable coolant delivery and stable tool engagement matter. Designed for engineers, machinists, and job-site versatility, this arbor provides direct through-tool cooling to protect cutting edges, improve chip evacuation, and extend tool life.

With a precision HSK63A shank, it delivers maximum rigidity and accuracy at speeds up to 25,000 RPM. It accommodates face mills with bore diameters from 16 mm to 32 mm, features a 16 mm spigot, and a 45 mm gauge length to ensure predictable alignment and smooth operation in demanding machining cycles.

• Through-Coolant Delivery to the Cutting Edge: Direct coolant flow keeps the cutting edge cooler, reduces built-up edge, improves chip evacuation, and extends tool life in high-speed milling.
• Rigid HSK63A Shank for Precision: High-precision fit minimizes runout and vibration, delivering consistent, accurate results even at 25,000 RPM.
• Broad Bore Compatibility and Stable Setup: Supports face mills with bore diameters from 16 mm to 32 mm and uses a 16 mm spigot with a 45 mm gauge length for reliable, repeatable tool changes and alignment.

This arbor helps you reduce rework, improve surface finishes, and speed up production cycles. The through-coolant system simplifies coolant routing while the rigid interface preserves precision across demanding operations, making it a dependable choice for upgrading existing setups or equipping high-speed milling cells.
