The Omega DV40 End Mill Holder with built-in coolant channels is engineered for high-speed milling in professional shops and serious home workshops. It brings a reliable solution for engineers, machinists, and buyers who demand precise toolholding and efficient cooling. With a 12 mm bore and a 160 mm gauge length, it accommodates standard end mills and integrates smoothly into your spindle setup.

Featuring a precision G2.5 balance and a maximum speed rating of 25,000 RPM, this holder delivers smooth operation with minimal vibration, helping you achieve accurate, repeatable cuts even at high feed rates.

• Built-in coolant channels for direct cooling: Delivers coolant right to the end mill edge, reducing heat, extending tool life, and improving chip evacuation for a cleaner cut.
• High-speed stability at 25,000 RPM: With a G2.5 balance, it minimizes vibration, supports precise cutting, and helps achieve a better surface finish at high speeds.
• Secure, rigid clamping and durable construction: Reliable tool holding minimizes runout, supports repeatable machining results, and reduces downtime.

This end mill holder is built to keep your workflow flowing: direct coolant delivery reduces heat buildup and prolongs tool life, while the rigid clamp maintains consistent alignment for repeatable results. The combination of high-speed capability and robust construction enables faster setups, cleaner finishes, and fewer interruptions caused by tool slips, making it a dependable choice for demanding milling tasks.
