The Omega DV40 End Mill Holder is a precision tool holder designed to securely mount end mills with a 25 mm bore, delivering stable, high-speed performance up to 25,000 RPM. Built for engineers, machinists, and hobbyists alike, it supports a range of diameters and shank sizes, providing versatile compatibility for a wide variety of milling tasks.

With a 160 mm gauge length and a Form AD/B interface, this holder delivers rigid support and repeatable accuracy across roughing and finishing operations. The construction uses balance grades of G2.5 (and G6.3) to minimize vibration, helping you maintain tight tolerances and a smooth cutting experience even at higher feeds.

• Secure, Flexible End‑Mill Holding: Precise construction and a robust clamping mechanism guarantee a secure grip on the end mill, preventing slip and maintaining accuracy even at high speeds.
• Smooth, Low‑Vibration Performance: Balance grades G2.5/G6.3 combined with a 15,000–25,000 RPM range dampen vibration, reduce chatter, and improve surface finish.
• Rigid, Reliable Alignment for Versatile Use: 25 mm bore with Form AD/B compatibility supports a wide range of diameters and shank sizes, delivering repeatable results and faster setup across milling tasks.

This end mill holder helps you streamline milling workflows by delivering secure tool retention, consistent runout, and steadier cutting across roughing and finishing passes. The combination of rigid gauge length and precise clamping reduces tool chatter and rework, saving time and boosting productivity. With reliable performance at up to 25,000 RPM and compatibility with a variety of tools, the Omega DV40 provides dependable, long-term value for shops and workshops seeking precise, repeatable milling results.
