The Omega Products Dual Contact DCBT40 Through Coolant Face Mill Arbor is designed for secure, precise mounting of face mill cutters. Built for high-speed milling and through-coolant delivery, it balances to G2.5 at 25,000 RPM, delivering stability with reduced vibration, and features a 40mm spigot and 55mm gauge length for robust toolholding.

• Through-Coolant Delivery for Efficient Cooling: Directs coolant where it’s needed most at the cutter interface, improving cooling, chip evacuation, and cutter life for demanding milling operations.
• Precisely Balanced for 25,000 RPM (G2.5): Optimized balance at high speed to minimize vibration, enhance surface finish, and extend tool life during continuous, high‑speed milling.
• Secure Mounting with 40mm Spigot and 55mm Gauge Length: Provides robust, repeatable engagement with compatible face mills, reducing runout and enabling reliable, quick tool changes in busy production environments.

This combination of through-coolant capability, precise high‑speed balance, and rigid mounting translates into cleaner finishes, higher productivity, and longer tool life. It’s a dependable choice for workshops and production floors that demand consistent results and minimal downtime in high‑speed milling applications.
