The Omega BT40 End Mill Holder (S/L20, Form AD) is built for high‑speed milling, delivering secure and precise tool retention for demanding CNC work. It features a 20 mm bore and a 35 mm gauge length, designed to hold standard BT40 end mills with stability at speeds up to 20,000 RPM. Ground to a G2.5 precision level, this holder ensures accurate tool seating and repeatable results for every pass.

• High‑speed capability up to 20,000 RPM: Maintains stable toolholding and accurate alignment even at fast cutting speeds, reducing chatter and improving surface finish.
• G2.5 precision seating: Delivers consistent tool seating and repeatable positioning across operations, lowering setup time and dimensional variation.
• BT40 compatibility with 20 mm bore and 35 mm gauge length: Provides robust, reliable clamping for standard BT40 tooling, supporting durable performance in demanding milling tasks.

Together, the Omega BT40 End Mill Holder helps you streamline workflow, reduce downtime, and achieve consistent milling results. The combination of high‑speed capability, precise seating, and durable construction translates to fewer tool changes, less rework, and more reliable performance across challenging applications in both professional shops and DIY environments.
