Omega Products BT40 Face Mill Arbor – FMB16 Through Coolant is designed to securely hold face milling cutters in BT40 spindle machines while delivering coolant directly to the cutting edge. Built for high-speed milling, it supports 15,000–25,000 RPM and features a 45 mm gauge length with Form AD/B + Cool, enabling precise, repeatable performance in demanding shop environments.

Through-Coolant channels are integrated into the arbor to channel coolant straight to the cutting edge, promoting efficient chip evacuation and cooler, more stable cuts. This design helps protect tools, reduce heat-related wear, and improve surface finishes on a variety of milling applications.

• Through-Coolant Delivery to the Cutting Edge: Built-in coolant channels feed coolant directly to the edge, improving chip evacuation, cooling, and cutting performance for longer tool life and cleaner finishes.
• High-Speed Stability and Precision: Engineered for 15,000–25,000 RPM with a precision rating of G2.5/G6.3, delivering consistent runout and accurate results even at top speeds.
• Rigid BT40 Interface with 45mm Gauge Length (Form AD/B + Cool): Provides secure, low-deflection tool seating on BT40 spindles with a 45 mm gauge length, supporting reliable engagement and repeatable tolerances; Form AD/B + Cool design supports coolant delivery and easy alignment.

This BT40 Face Mill Arbor delivers dependable performance across a range of milling tasks—from standard face milling to demanding high-speed operations. With direct coolant delivery, rigid seating, and precise high-speed capability, it helps you reduce downtime, improve finish quality, and maintain tight tolerances, all while supporting efficient, productive workflows.
