The Omega DV40 End Mill Holder with built-in coolant channels is engineered for high-speed CNC milling, delivering coolant directly to the cutting edge to reduce heat and extend tool life. It’s designed for engineers, buyers, tradespeople, hobbyists, and anyone needing reliable, repeatable tool holding at up to 25,000 RPM. With a 6 mm bore size and a 160 mm gauge length, it provides a compact, rigid interface that supports precise, consistent machining.

• Built-in coolant channels deliver direct edge cooling: Direct coolant delivery to the cutting edge reduces heat buildup, helps prolong tool life, and improves chip evacuation for a cleaner, more efficient cut.
• High-speed stability with G2.5 balance: The G2.5 balance grade minimizes vibrations at speeds up to 25,000 RPM, enabling smoother cuts, tighter tolerances, and more consistent finishes.
• Secure, rigid tool holding: A reliable clamping mechanism and robust construction keep the end mill firmly in place, improving repeatability and reducing runout during demanding milling operations.

This combination of coolant delivery, precision balance, and secure clamping translates into real-world benefits: longer tool life, cleaner chips, steadier cuts, and more consistent results across jobs. It helps streamline setups, reduce downtime, and improve overall milling performance for a wide range of applications.
