The Omega BT40 End Mill Holder (S/L08, Form AD/B) is a precision tool holder designed for BT40 spindle systems. It securely supports end mills with an 8 mm bore and a generous 100 mm gauge length, delivering stable tool projection and dependable retention during high-speed milling. Built to withstand demanding jobs, it helps operators maintain consistent accuracy from setup to finish.

Crafted from high-quality materials, this holder emphasizes durability and stability, so you can rely on it for repetitive, long-running machining tasks across a wide range of materials and applications.

• 8 mm Bore Size for Secure Tooling: Fits standard 8 mm end mills with firm, slip-free clamping to minimize movement and improve reliability during cuts.
• 100 mm Gauge Length for Enhanced Rigidity: Longer gauge length reduces tool deflection under load, delivering straighter cuts and steadier performance at high speeds.
• G2.5 Precision Rating for Repeatable Performance: Tight seating tolerance ensures consistent tool alignment and repeatable results across multiple parts and setups.

With these design details, the BT40 End Mill Holder translates into real-world benefits: faster, more predictable tool changes; reduced runout and chatter; and improved surface finish. It supports efficient workflows in both busy workshops and precise job shops, helping you achieve dependable results with every milling pass.
