Description
The Omega BT50 Face Mill Arbor with Through Coolant is a precision mounting solution designed for BT50 spindle machines. It securely holds face milling cutters while delivering coolant directly to the cutting edge, optimizing cooling and chip evacuation for better performance in demanding milling tasks.
Built for high-speed operation, this arbor supports a wide speed range from 15,000 to 25,000 RPM and delivers tight, consistent results with precision ratings of G2.5 / G6.3. Featuring a 160 mm gauge length and Form AD/B + Cool, it provides a robust, ready-to-use setup that suits professional shops and serious hobbyist workflows alike.
- Through-Coolant Channel System: Built-in coolant paths deliver coolant directly to the cutting edge, enhancing cooling, improving chip evacuation, and helping extend tool life during high-speed milling.
- High-Speed, Precision Performance: Optimized for up to 25,000 RPM with tight tolerances, ensuring stable concentricity and repeatable cuts at speed for cleaner finishes and predictable results.
- BT50 Fit with Gauge Length and Coolant Form: The 160 mm gauge length and AD/B + Cool form provide a secure, rigid interface with BT50 spindles while maintaining integrated cooling for reliable, efficient setups.
This combination of through-coolant delivery, precise high-speed performance, and a robust BT50 interface helps streamline milling workflows, reduces downtime between tool changes, and supports consistent results across repetitive operations.
