The Omega BT40 End Mill Holder is a precision tool holder designed for BT40 spindle systems. It features a 25 mm bore size to securely accommodate standard 25 mm shanks, and a 70 mm gauge length that provides stable support during demanding milling operations. Form AD construction helps ensure reliable seating and compatibility with common spindle setups.

Engineered for high-speed work, this holder delivers precise tool positioning up to 20,000 RPM with a G2.5 accuracy rating, so you can trust consistent results across jobs and batches.

• High-speed capability up to 20,000 RPM: Supports fast material removal while maintaining concentric, stable tool control for reliable finishes and reduced cycle time.
• G2.5 precision for repeatable positioning: Ensures exact concentricity and repeatable seating for consistent tool paths and tight tolerances across operations.
• 25 mm bore size and 70 mm gauge length for stability: Large bore accepts standard 25 mm tools while the 70 mm gauge length provides a balanced, rigid overhang that resists deflection during demanding cuts.

With its robust construction and precise seating, the Omega BT40 End Mill Holder helps minimize tool chatter and deflection, resulting in steadier finishes, faster setups, and fewer rechecks. It’s a dependable choice for professional shops, job shops, and serious hobbyists who demand reliable performance in high-speed milling.
