Omega BT40 End Mill Holder, S/L20, is designed for BT40 spindle systems and high-speed milling applications. This precision holder provides secure, repeatable tool seating with a 20 mm bore and a generous 200 mm gauge length, making it a reliable foundation for demanding machining work.

Crafted for durability and stability, it is machined to tight tolerances to minimize runout and vibration. The result is consistent tool alignment, extended tool life, and dependable performance across a range of materials and job sizes—from quick prototyping to production runs.

• 15,000 RPM maximum speed: Optimized for high-speed milling with stable tool seating, helping reduce chatter and maintain consistent cutting performance at elevated spindle speeds.
• 20 mm bore size: Provides secure, reliable clamping for standard 20 mm tooling shanks and enables quick, confident tool changes with repeatable seating.
• 200 mm gauge length: Offers extended reach while preserving rigidity, enabling accurate machining in deep pockets and long-reach applications within the BT40 interface.

Built for reliability, this holder integrates BT40 compatibility with a precision standard (G6.3) to support tight runout and repeatable results. It helps streamline setups, reduce downtime, and deliver predictable performance across challenging milling tasks, whether in a workshop, job shop, or production environment.
