The Omega BT40 End Mill Holder is a precision toolholding solution designed for BT40 spindle applications. Built to keep end mills securely aligned during high-speed machining, it offers stable seating and repeatable performance. With a 12 mm bore and a 63 mm gauge length (Form AD/B), this holder fits standard BT40 tooling and supports high-speed operations up to 20,000 RPM while maintaining tight G2.5 accuracy for consistent results.

Manufactured from high-quality materials, the holder emphasizes durability and stability in true production environments. Its robust construction minimizes runout and vibration, helping you achieve smoother finishes, longer tool life, and dependable performance across long runs and challenging materials.

• G2.5 precision for repeatable accuracy: Ensures tool seating is consistently centered and reduces runout for reliable pocketing and finish.
• 12 mm bore for secure, uniform clamping: Provides a strong grip on the tool shank with minimal deflection, even at high speeds.
• 63 mm gauge length for stability and reduced chatter: Shorter overhang improves rigidity and helps maintain accuracy during aggressive milling.

By delivering consistent tool seating and reduced runout, this BT40 End Mill Holder helps you achieve better surface finishes, extend tool life, and minimize downtime caused by misalignment. It's a dependable choice for professionals who demand productive setups, repeatable results, and quiet, stable operation in CNC milling, prototype work, or high-speed production.
