The Omega BT40 Face Mill Arbor with Through Coolant is designed to securely hold face milling cutters in BT40 spindle machines while delivering coolant directly to the cutting edge. This setup helps maintain consistent tool performance in high-speed milling applications across shop floors and production environments.

With a 100mm gauge length and a Form AD/B + Cool configuration, it’s built for reliable alignment and compatibility with standard BT40 tooling, enabling smooth tool changes and stable operation at high speeds.

• Through-Coolant Delivery: Built-in coolant channels feed the cutting edge, improving chip evacuation, reducing heat buildup, and enhancing finish quality even during aggressive milling.
• BT40 High-Speed Precision: Optimized for 15,000–25,000 RPM with tight runout (G2.5/G6.3), delivering repeatable accuracy and reliable performance in demanding milling operations.
• 100mm Gauge Length + AD/B Form: Stable engagement in BT40 spindles with a 100mm gauge length and Form AD/B + Cool design for secure tool retention and quick, confident changes.

This arbor supports efficient, high-speed milling workflows by combining precise tool retention with effective coolant delivery. Expect consistent results, reduced downtime, and improved cutting performance across a range of face milling applications from production machining to precision finishing.
