Omega Products BT50 Combi Shell Mill Arbor - COMBI40 - 15,000 RPM - G6.3 - 75mm Gauge Length

The BT50 Combi Shell Mill Arbor (COMBI40, 75mm Gauge Length) is a purpose-built mounting interface that lets you attach shell milling cutters to BT50 spindles with accuracy and stability. Designed for high-speed milling, it supports precise positioning and reliable cutter engagement at speeds up to 15,000 RPM.

Ideal for engineers, machinists, and workshops that demand tight tolerances and efficient tool changes, this arbor combines a robust BT50 interface with the COMBI40 platform to deliver consistent performance across demanding milling tasks.

• BT50 COMBI40 Mounting Interface: Securely mounts shell milling cutters on BT50 spindles, providing a rigid, repeatable seating surface that improves stability and accuracy during cuts.
• High-Speed Capability up to 15,000 RPM: Optimized for fast shell milling, helping you achieve shorter cycle times while maintaining consistent cutting performance and surface finish.
• G6.3 Precision Rating: Tight runout and dependable dimensional control ensure repeatable results across tool changes and multiple jobs.

By delivering a stable BT50 interface with precise seating, you’ll experience smoother cutting action, less vibration, and more consistent finishes. The 15,000 RPM capability unlocks faster cycles without sacrificing accuracy, while the 75mm gauge length keeps tools balanced and predictable through multiple operations. In daily production, this means less downtime for tool changes, fewer reworks, and more reliable throughput.
