Omega Dual Contact DCBT40 Through-Coolant Face Mill Arbor is engineered to securely mount face mill cutters in high-speed milling environments. Its through-coolant design supports efficient chip evacuation and cooler cutting, making it ideal for shops and professionals who run demanding milling cycles and value repeatable, precise results. With a 22 mm spigot size and a 160 mm gauge length, this arbor provides robust compatibility and dependable alignment across multiple cutters.

Balanced for stability at speed, the arbor is tuned to G2.5 at 25,000 RPM, delivering smooth operation, reduced vibration, and better surface finish during aggressive milling.

• Through-Coolant capability: Delivers coolant directly through the arbor to the cutter, improving chip removal, reducing heat buildup, and extending tool life for cleaner cuts and longer cutter life.
• High-speed balance at 25,000 RPM: Precision G2.5 balancing minimizes vibration in demanding milling cycles, enabling tighter tolerances and better surface finishes.
• Rigid 22 mm spigot and 160 mm gauge length: Provides secure seating and repeatable alignment with face mills, supporting quick setup and consistent performance across jobs.

This arbor helps you maximize milling efficiency by delivering reliable toolholding, stable cutting, and repeatable results across long production runs. Its through-coolant design, combined with precise high-speed balance and robust sizing, reduces downtime, improves finish quality, and supports faster setup and consistent performance in demanding milling applications.
