The Omega Products HSK63A Face Mill Arbor with Through Coolant is built for high-speed milling where tool cooling and precision engagement matter. The precision HSK63A shank delivers maximum rigidity and accuracy, helping you maintain tight tolerances and smooth tool paths even at elevated RPMs.

Designed to work with through-coolant face mills, this arbor uses a G2.5 coolant system to deliver coolant directly to the cutting edge, improving tool life and chip evacuation. It accommodates face mills with bore diameters from 16 mm to 32 mm, features a 16 mm spigot, and a 100 mm gauge length, and is rated for spindle speeds up to 25,000 RPM.

• Through-Coolant Delivery (G2.5): Direct cooling at the cutting edge reduces heat, extends tool life, and enhances chip evacuation for cleaner, more consistent cuts.
• Rigid HSK63A Interface: A precise shank design delivers maximum rigidity and minimal runout, supporting accurate machining at high speeds.
• Versatile Bore Range with High-Speed Stability: Fits face mills with bores from 16 mm to 32 mm, featuring a 16 mm spigot and 100 mm gauge length for stable engagement and reliable performance up to 25,000 RPM.

This arbor is designed to improve productivity by delivering steady, repeatable results across demanding milling tasks. The through-coolant system helps manage heat and chips, while the rigid HSK63A connection keeps tooling true, enabling consistent finishes and reduced downtime across production runs. With its compact 16 mm spigot and substantial 100 mm gauge length, setup remains straightforward and dependable for a wide range of face mills within the specified bore range.
