It enables efficient coolant delivery directly to the cutting edge, helping you achieve consistent, high-quality results in demanding milling operations.
- Through-Coolant Delivery: Built-in coolant channels route coolant straight to the cutting edge, improving chip evacuation, reducing heat, and supporting longer tool life even at high feedrates.

Designed for engineers, machinists, and shop floor operators, this arbor helps you maximize productivity by delivering dependable alignment, superb cooling, and durable performance in high-speed face milling applications. Its robust BT50 interface, precise tolerance, and integrated coolant capability work together to reduce downtime, improve surface finish, and support repeatable machining outcomes across production runs.
