The Omega BT40 End Mill Holder is a precision tool holder designed for BT40 spindle systems. It is ideal for engineers, machinists, tradespeople, hobbyists, and anyone who needs secure, repeatable tool retention in high-speed milling applications.

Engineered with Form AD/B design and a 25 mm bore, this holder keeps end mills aligned and firmly clamped at speeds up to 20,000 RPM, delivering stable performance and reduced runout through every cut. Built from high-quality materials for durability, it provides long-lasting reliability in demanding shop environments.

• G2.5 Precision for Repeatable Accuracy: Ensures precise tool positioning and consistent results across multiple cycles, helping you maintain tight tolerances and a smooth finish.
• 20,000 RPM Rated for High-Speed Milling: Designed to withstand fast spindle speeds, boosting material removal rates while preserving tool life and accuracy.
• 25 mm Bore with 100 mm Gauge Length: Provides secure clamping and stable tool projection, delivering rigidity and predictable performance during demanding cuts.

With these capabilities, the BT40 End Mill Holder helps you streamline setup, reduce downtime, and achieve repeatable, quality results across projects. The combination of precise fit, high-speed capability, and durable construction gives you confidence to push harder cuts, maintain consistent performance, and extend tool life in busy shop environments.
