Description
Designed for BT40 spindle machines, the Omega BT40 Face Mill Arbor with Through Coolant securely holds face milling cutters while delivering coolant directly to the cutting edge. This through-coolant design ensures efficient cooling and chip control during high-speed milling.
Engineered for speeds up to 25,000 RPM with precision to G6.3, it delivers stable, repeatable performance. The 160 mm gauge length and Form AD/B interface simplify setup and alignment in standard BT40 tooling for effortless integration into existing rigs.
- Through-Coolant Delivery: Built-in coolant channels feed the cutting edge, improving chip evacuation, reducing heat buildup, and extending tool life for consistent finishes.
- High-Speed Stability: Optimized for up to 25,000 RPM with tight runout and rigid clamping, delivering reliable, precise results even in demanding materials.
- 160mm Gauge Length, Form AD/B: Matches standard BT40 configurations for quick, repeatable seating and easy integration into existing milling setups.
In daily use, this arbor helps you maintain a smooth, productive workflow. The integrated coolant path keeps tooling cooler and cutting edges protected, while the rigid BT40 interface and precise gauge length ensure fast, confident setups with repeatable results. Together, these advantages translate to better surface finishes, fewer reworks, and improved overall milling efficiency.
