Omega's HSK63F Face Mill Arbor with Through Coolant is a precision tool accessory designed for high-speed milling up to 25,000 RPM. It is engineered with a G2.5 balance level to deliver enhanced precision and reliability in heavy-duty machining, making it suitable for engineers, fabricators, and technicians who demand consistent results from their face milling setups.

With a 22 mm shank and a 50 mm gauge length, this arbor pairs seamlessly with face mills that have Weldon or ISO 3937 (DIN 6359) flat shanks. The through coolant system delivers coolant directly to the cutting edge, promoting efficient chip evacuation, cooler cutting, and extended tool life—especially in demanding materials and tough production runs. The HSK63F taper design ensures high clamping forces and rigidity for optimal cutting performance.

• Through Coolant delivery to the cutting edge: Directs coolant where it’s needed for improved chip evacuation, reduced heat buildup, and longer tool life in aggressive milling conditions.
• G2.5 balance for high-speed precision: Maintains stable runout and smooth operation up to 25,000 RPM, minimizing vibration and delivering consistent surface finish.
• Rigid HSK63F taper with strong clamping: High clamping forces and inherent rigidity reduce deflection, improve accuracy, and support reliable performance in heavy-duty machining.

Designed to integrate easily into demanding production workflows, this arbor helps you maintain steady feeds, predictable results, and longer tool life across long milling campaigns. Its robust construction and compatibility with common flat-shank face mills simplify setup and reduce downtime, so you can focus on quality, throughput, and finishing tasks with confidence.
