Cartridges

Top Notch™ threading cartridges are versatile and high-quality tools ideal for multiple applications. One of their key features is the secure mounting and clamping system, which ensures that your tools are held firmly in place during operations. This not only enhances the precision of your work but also contributes to the safety and efficiency of your machining processes. Cartridges are completely interchangeable in any boring bar, head, or tooling block manufactured to ANSI or ISO standards.
