The Omega DV40 End Mill Holder combines a robust 32 mm bore with a 65 mm gauge length and Form AD interface to securely accommodate a wide range of end mills and shank sizes. Engineered for rigidity and repeatable seating, it delivers stable tool performance up to 20,000 RPM for consistent results in milling operations. Whether you’re a professional machinist, shop planner, or dedicated maker, this holder helps you reduce chatter, protect tolerances, and maintain finish quality across roughing and finishing passes. Its precise construction and reliable clamping mechanism ensure the end mill stays firmly in place, minimizing slip and maximizing productivity in demanding milling tasks. Secure, precise clamping: A robust locking mechanism and tight bore grip keep the end mill from slipping, preserving dimensional accuracy and surface finish even under heavy cutting loads. Balanced, smooth rotation: Balance grades G2.5/G6.3 and a rigid interface minimize vibration and chatter, enabling clean cuts at up to 20,000 RPM for better tool life and finish. Rugged Form AD design for reliable seating: Durable construction with a Form AD interface ensures easy integration into standard milling setups and consistent seating across repeated tool changes. This combination of secure clamping, vibration control, and durable design translates to faster setup, reduced downtime, and more predictable results across a variety of milling applications.
