The Omega Products HSK63A Face Mill Arbor with Through Coolant is built for demanding high-speed milling on modern CNC centers. Designed for engineers, machinists, buyers, tradespeople, and hobbyists who value precision and productivity, this arbor provides stable, rigid support for face mills while delivering coolant directly to the cutting edge. With a G2.5 through-coolant system, it enhances tool life, chip evacuation, and surface finish at speeds up to 25,000 RPM. Equipped with a 22 mm spigot and a 160 mm gauge length, it ensures fast, repeatable setups and compatibility with face mills having bores from 16 mm to 32 mm.

• Through-Coolant Delivery: G2.5 through coolant directs coolant right to the cutting edge, improving tool life, helping chip evacuation, and supporting cleaner finishes at high speeds.
• Rigid HSK63A Shank: Precision HSK63A interface provides maximum rigidity and reduced runout, delivering stable performance and consistent results at up to 25,000 RPM.
• Broad Bore Compatibility & Precise Dimensions: Accepts face mills with 16–32 mm bores and features a 22 mm spigot with a 160 mm gauge length for quick, reliable setup and broad tooling compatibility.

This arbor helps you keep production moving by reducing heat-related wear, improving surface quality, and cutting setup time. The through-coolant system enhances performance on demanding materials, while the rigid interface maintains precise alignment across long runs. If you’re upgrading a high-speed milling setup or equipping a production cell, this arbor offers dependable, repeatable results across a range of applications.
