The Omega BT40 Face Mill Arbor with Through Coolant is a precision tool holder designed to securely mount face milling cutters in BT40 spindle machines while delivering coolant directly to the cutting edge. Built for high-speed milling, it supports speeds from 15,000 to 25,000 RPM and offers stable, repeatable performance across a wide range of applications—from general roughing to finish work. Its 200 mm gauge length provides the rigidity needed for accurate tool alignment and consistent cut quality.

• Through-Coolant Delivery to the Cut: Integrated coolant channels feed coolant straight to the cutting edge, improving chip evacuation, reducing heat buildup, and helping extend tool life during demanding milling operations.
• BT40 Interface with 200 mm Gauge Length: A robust BT40 connection and extended gauge length maximize axial rigidity and repeatable seating, delivering steady performance and minimal runout across multiple tools.
• High-Speed Precision Performance: Designed for 15,000–25,000 RPM operation with precise tolerances (G2.5/G6.3), delivering reliable stability and consistent results at high speeds.

This combination of secure retention, efficient cooling, and high-speed accuracy makes the BT40 Face Mill Arbor a dependable choice for shops aiming to reduce downtime, improve chip control, and achieve repeatable finished surfaces in a variety of milling tasks.
