Description
The BT50 Machinable Boring Bar Blank is a precision-ready starting point for engineers and machinists who design custom boring bars. Sized for BT50 spindle setups, it uses a BT40 connection for straightforward integration into BT50 machines, letting you tailor a tool to your exact boring requirements. With a 97 mm diameter and 315 mm gauge length, this blank provides a solid base for reliable, repeatable results across a range of applications.
Manufactured from high-quality material, this boring bar blank is built for durability and stability during demanding milling and drilling operations. Its smooth surface and accurate dimensions help you achieve consistent bore sizes and finishes, while giving you the freedom to shape the final bar to your specific geometry.
- BT40 Connection for Easy Spindle Integration: The BT40 interface makes it simple to drop into BT50 spindles, reducing setup time and preventing misalignment so you can start cutting sooner.
- Rigid 97 mm Diameter and 315 mm Gauge Length: Large diameter with extended gauge length provides added stiffness and reduced tool deflection, delivering consistent bore quality even on longer, deeper cuts.
- Machinable Blank for Custom Boring Bars: Use this as a customizable foundation—mill, grind, or rework to your exact final geometry, enabling you to create a tailored boring bar that matches your workpiece material and machining strategy.
By starting with a precisely dimensioned, durable blank, you can streamline tool development, improve bore accuracy, and reduce downtime on repetitive jobs. The combination of BT40 compatibility, solid construction, and machinability gives you a reliable platform for producing repeatable, high-quality boring bars that fit a wide range of BT50 setups.
