The Omega BT50 Face Mill Arbor with FMB40 through coolant is designed to securely hold face milling cutters in BT50 spindle machines while delivering coolant directly to the cutting edge. This setup helps maintain optimal cutting temperatures and provides efficient chip evacuation for cleaner, more consistent results.

Engineered for high-speed milling, it supports speeds from 15,000 to 25,000 RPM and offers precise runout performance (G2.5/G6.3) to deliver stable, repeatable results across demanding jobs. The combination of Form AD/B with through-coolant channels and a 250 mm gauge length makes it adaptable to a wide range of milling configurations.

• Through-Coolant Delivery: Built-in coolant channels route coolant directly to the cutting edge, improving chip evacuation, reducing heat buildup, and helping extend tool life in tough milling applications.
• High-Speed Stability and Precision: Designed for reliable performance up to 25,000 RPM with tight tolerance (G2.5/G6.3), delivering consistent finishes and repeatable results even on demanding production work.
• BT50/FMB40 Compatibility with 250 mm Gauge Length: The BT50 spindle compatibility via the FMB40 interface and a 250 mm gauge length provide flexible, balanced mounting and straightforward setup across a broad range of milling tasks.

This combination of direct coolant delivery, high-speed precision, and versatile mounting helps you finish jobs faster, maintain cooler tooling, and reduce downtime—supporting clean finishes, better productivity, and reliable performance on BT50 milling centers.
