The Omega BT40 Face Mill Arbor with Through Coolant is designed to securely mount face milling cutters in BT40 spindle machines while delivering coolant directly to the cutting edge. This through-coolant design improves heat management and chip evacuation, helping you maintain cutting performance in high-speed milling environments.

Ideal for shops and engineers tackling demanding milling tasks, it offers reliable setup and consistent results.

• Through‑Coolant delivery to the cutting edge: Built‑in coolant channels channel coolant directly to the tool’s edge, improving heat control, chip evacuation, and cutting stability for longer tool life in high‑speed milling.
• High‑speed stability and precision: Optimized for 15,000–25,000 RPM with a precision rating of G2.5/G6.3, delivering repeatable, accurate results even under demanding milling conditions.
• BT40 compatibility with 45mm gauge length (Form AD/B + Cool): Securely mounts in BT40 spindles with a 45mm gauge length and coolant‑through capability, enabling fast setup and reliable tool changes without sacrificing rigidity.

With Through Coolant and a BT40 interface, this arbor helps deliver cleaner finishes and longer tool life while reducing downtime from overheating or clogged tools. The 15k–25k RPM capability paired with precise runout guarantees dependable, repeatable performance across production runs and job‑shop work, making it a trusted choice for milling operators who demand speed, accuracy, and reliability.
