The Omega BT40 Machinable Boring Bar Blank is a precision-engineered cylindrical blank designed to become your next custom boring bar. With a 63 mm diameter and a 250 mm gauge length, it provides a robust, ready-to-machine foundation for high-precision boring operations. The BT40 connection ensures compatibility with a wide range of spindles, letting you drop this blank into your BT40 setup quickly and with minimal alignment effort.

Ideal for shop floors and project work across manufacturing, metal fabrication, and hobbyist machine shops, this blank offers a reliable platform to tailor tool geometry, length, and tips to your exact needs. Built from high-quality materials, it resists deformation under heavy cuts, helping you maintain consistent hole sizes and smooth finishes.

• Precise, ready-to-machine dimensions: The 63 mm diameter and 250 mm gauge length provide a stable, concentric core that reduces setup time and supports repeatable bore quality across cycles.
• BT40 compatible interface: Easy installation into BT40 spindles with clean seating and minimal runout, so you can start machining sooner and with confident accuracy.
• Durable, machinable construction: Designed to withstand cutting forces and heat while maintaining dimensional stability, delivering reliable performance through demanding operations.

This boring bar blank empowers you to craft a tool perfectly matched to your application, improving hole accuracy, reducing downtime, and delivering consistent results across jobs. By starting with a stable, high-quality blank, you can confidently tailor length, geometry, and tip configurations to optimize your workflow and achieve better overall performance.
