The Omega BT50 Face Mill Arbor with Through Coolant (FMB22 Through Coolant) is a precision mounting solution designed to securely hold face milling cutters in BT50 spindle machines while delivering coolant directly to the cutting edge. The through-coolant design enhances chip evacuation and helps maintain optimal cutting temperatures for improved performance in demanding milling operations.

Engineered for high-speed work, this arbor accommodates 15,000 to 25,000 RPM and uses tight tolerances (G2.5 / G6.3) to deliver stable, repeatable accuracy at speed. It features a 100 mm gauge length and Form AD/B compatibility, plus integrated coolant channels, so setup is straightforward and dependable across a variety of cutting tasks.

• Through-Coolant Delivery: Built-in coolant channels feed coolant directly to the cutting edge, improving chip evacuation, cooling, and tool life during high-speed milling.
• High-Speed Stability and Precision: Designed for 15,000–25,000 RPM with G2.5/G6.3 tolerances, ensuring consistent runout control and repeatable results at top speeds.
• BT50 Compatibility, Gauge Length, and Form AD/B + Cool: Specifically matched to BT50 spindles with a 100 mm gauge length for reliable seating; Form AD/B compatibility and integrated through-coolant design support durable, leak-free operation.

This arbor helps you achieve cleaner finishes, longer tool life, and reliable throughput by combining secure mounting, precise alignment, and efficient cooling. It simplifies high-speed milling workflows, reduces downtime, and delivers consistent results across multiple jobs and materials.
