The Omega BT50 Face Mill Arbor with Through Coolant (FMB22) is a precision tool holder designed to fit BT50 spindle machines. It securely locates face milling cutters and is built for high-speed milling in demanding shops. With a 200 mm gauge length and Form AD/B + Cool interface, this arbor delivers reliable seating and repeatable performance across jobs.

Equipped with built-in through-coolant channels, coolant flows directly to the cutting edge to improve chip evacuation, control heat, and maintain cutting performance even during extended or aggressive cuts.

• Through-Coolant delivery to the cutting edge: Direct coolant flow reduces heat, improves chip removal, and helps extend cutter life for cleaner finishes and longer tool life in demanding passes.
• High-speed stability and precision: Optimized for 15,000–25,000 RPM with a tight G2.5/G6.3 tolerance, delivering consistent runout control and accurate results at speed.
• Secure BT50 interface with 200 mm gauge length: Rugged seating with FMB22 through-coolant compatibility and Form AD/B + Cool design enables quick changes and repeatable performance in busy production setups.

This arbor streamlines high-speed face milling by combining reliable alignment, efficient coolant delivery, and a ready-to-use BT50 interface. The result is faster changeovers, lower downtime, and consistently solid finishes across a range of cutter configurations and materials.
