Modular WST Interchangeable Tip Drill for Demanding Tasks

The WST interchangeable tip drill represents a reliable base for professional drilling processes in machining technology. This modular holder system is precisely designed for replaceable drill heads in the diameter range from 27.00 to 27.78 mm. It combines the flexibility of a multi-part holder with the robustness of a solid drill, thereby supporting efficient workflows in modern manufacturing.

Please pay attention to the Holder/drill bit combinations!
Only drill bits with a diameter of 27,00-27,78 mm fit on these supports.

Applications

This drill body is a well-thought-out solution for versatile applications on CNC machining centers and modern turning machines. When paired with the matching solid carbide inserts, the system opens up varied possibilities for producing precise holes in mechanical engineering, toolmaking, and fixture construction. By offering three practical length options (3xD, 5xD, and 8xD), different drilling depths can be achieved with flexibility and process reliability.

Special features

The modular design of this holder system supports a sustainable reduction in tooling costs, as only the actual cutting tip needs to be replaced when worn. This replacement is performed quickly and can often be carried out directly in the spindle, minimizing non-productive machine downtime. The highly resilient base body features excellent rigidity, creating ideal conditions for smooth, low-vibration machining even at extended tool overhangs.
