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. Built for durability and consistent performance, it's ideal for shops and job sites that demand reliable tooling for high-speed milling, from mold and die work to general precision machining.

With a speed range of 15,000 to 25,000 RPM and precision ratings of G2.5/G6.3, this arbor maintains stability under heavy cutting. The 100 mm gauge length provides rigidity for longer reach applications, while Form AD/B mounting and integrated through-coolant channels ensure coolant reaches the cutting edge for effective chip control and improved surface finish.

• Through-Coolant Delivery Direct to the Cut Edge: Built-in coolant channels feed coolant right to the cutting edge, improving cooling, chip evacuation, and tool life in high-speed milling.
• High-Speed Stability and Precision: Engineered for 15,000–25,000 RPM with tight runout (G2.5/G6.3), delivering reliable, repeatable accuracy under demanding loads.
• 100 mm Gauge Length with Form AD/B and FMB16 Through-Coolant: Provides rigid toolholding in BT40 spindles while enabling direct through-coolant delivery for consistent seating and cleaner finishes.

Choose this arbor to reduce downtime, achieve consistent part quality, and simplify tool changes. The combination of robust construction, precise alignment, and integrated cooling helps you maintain production throughput, protect tool life, and finish parts with confidence across a wide range of milling tasks.
