Omega Products HSK63A Face Mill Arbor with Through Coolant is built for high-speed milling where precision and tool life matter. It uses a precision HSK63A shank and a G2.5 through-coolant system to deliver coolant directly to the cutting edge for efficient cooling and chip evacuation.

Designed for face mills with bores from 16 mm to 32 mm, it runs at speeds up to 25,000 RPM and features a 16 mm spigot with a 160 mm gauge length for stable, repeatable setups.

• Through-Coolant Delivery: Direct coolant to the cutting edge improves chip evacuation, reduces heat, extends tool life, and helps maintain tight tolerances during high-speed milling.
• Rigid HSK63A Interface: The precision HSK63A shank provides maximum rigidity and balance, minimizing runout and ensuring consistent accuracy at speeds up to 25,000 RPM.
• Versatile Bore Range and Mounting: Accepts face mills with bore diameters from 16 mm to 32 mm, features a 16 mm spigot and 160 mm gauge length for stable, repeatable tool changes across a wide range of tooling.

By delivering coolant directly to the cutting edge, providing a rigid HSK63A interface, and accommodating 16–32 mm bore face mills with a 16 mm spigot and 160 mm gauge length, this arbor helps you push faster feeds, achieve cleaner finishes, and reduce tool wear. It supports reliable setups, minimizes downtime, and delivers consistent performance across demanding milling jobs.
