Omega Products BT40 Face Mill Arbor with Through Coolant is designed to securely hold face milling cutters in BT40 spindle machines while delivering coolant directly to the cutting edge. This setup supports high-speed milling operations in shops and job sites, helping you achieve cleaner cuts and better chip management.

With a speed range of 15,000–25,000 RPM and precision ratings of G2.5/G6.3, it provides stable accuracy at high speeds for consistent surface finish and longer cutter life. The Form AD/B configuration plus built-in coolant channels ensure reliable seating and efficient coolant delivery to the cutting edge.

• Direct Through-Coolant delivery: Built-in coolant channels feed fluid right to the cutting edge, improving chip evacuation, reducing thermal wear, and helping maintain cutter life at high speeds.
• High-speed stability and precision: Designed for 15,000–25,000 RPM with tight balance and G2.5/G6.3 precision, delivering consistent runout and surface finish in demanding aluminum and steel milling applications.
• Form AD/B with 100 mm gauge length: Provides a secure, repeatable seating solution compatible with standard BT40 tooling sets, with a 100 mm gauge length for rigidity and easy setup.

This BT40 Face Mill Arbor helps you streamline setups, boost machining reliability, and improve overall productivity. Direct coolant delivery reduces downtime for chip clearance and coolant piping, while the high-speed capability and precise alignment keep tools cutting cleanly longer, reducing tool changes and scrap. The result is smoother throughput, better part quality, and confidence in challenging high-speed milling jobs.
