Omega Products BT40 Face Mill Arbor - FMB32 Through Coolant - 25,000RPM - G2.5 - 160mm Gauge Length - Form AD/B + Cool

The Omega BT40 Face Mill Arbor with Through Coolant is a precision spindle accessory designed to securely hold face milling cutters in BT40 machines while delivering coolant directly to the cutting edge. This through-coolant design helps keep tools cooler, reduces chip buildup, and supports consistent performance at high speeds.

With a speed range of 15,000 to 25,000 RPM, a gauge length of 160 mm, and Form AD/B compatibility (plus the FMB32 Through Coolant configuration), it delivers stable, accurate results in production environments and workshop setups. The precision rating of G2.5/G6.3 ensures tight runout and reliable finishes across demanding milling tasks.

• Through-Coolant Channeling: Delivers coolant directly to the cutting edge for heat control, faster chip evacuation, and longer tool life during high-speed milling.
• High-Speed Precision (15,000–25,000 RPM; G2.5/G6.3): Maintains tight tolerances and stable performance across the full speed range, reducing runout and delivering consistent finishes.
• BT40 Mounting with 160 mm Gauge Length: Designed for BT40 spindle machines with a 160 mm gauge length and Form AD/B, delivering reliable seating, easy setup, and quick tool changes.

This BT40 arbor is built to keep pace with busy shop floors. By delivering coolant right to the edge, it helps maintain tool life, minimizes heat-related wear, and supports clean, consistent finishes. The combination of high-speed capability, precise tolerance, and stable mounting means fewer rework cycles and smoother changeovers—so you can complete more parts in less time with confidence.
