The Omega BT40 Face Mill Arbor with Through Coolant securely holds face milling cutters in BT40 spindle machines while delivering coolant directly to the cutting edge. Designed for high-speed milling up to 25,000 RPM, this arbor helps maintain chip evacuation and cutting efficiency even when cutting tough materials.

Featuring FMB16 through coolant, a 160 mm gauge length, and Form AD/B + Cool, it provides reliable seating and easy integration with established BT40 tool layouts. Built for durability and precise alignment, it supports demanding milling tasks with consistent performance.

• Efficient Through-Coolant Delivery: integrated coolant channels feed coolant straight to the cutting edge, improving chip removal, reducing heat, and extending cutter life for cleaner finishes.
• High-Precision, High-Speed Performance: optimized for 15,000–25,000 RPM with precision ratings G2.5/G6.3, delivering stable cuts and repeatable accuracy in fast milling directions.
• Secure BT40 Interface with 160 mm Gauge Length: Form AD/B + Cool and 160 mm gauge length ensure reliable cutter seating, quick tool changes, and dependable performance in busy machining environments.

This arbor is a practical choice for shops aiming to improve productivity, reduce downtime, and achieve consistent, high-quality surface finishes in high-speed face milling applications. Its through-coolant design and robust BT40 interface help maintain stable, long-lasting performance across demanding production runs.
