When using the 5xD or 8xD drill body, we recommend reducing the feed rate to 85% or 70%.
Applications
These interchangeable drill tips are ideally suited for universal drilling operations in the metalworking industry. Whether machining cast iron or various steel grades, this tool opens up flexible application possibilities with consistently high hole quality. Designed for use with WST D27.0 holder bodies in 3xD, 5xD, and 8xD lengths, even deep and complex boreholes can be realized in a stable and dimensionally accurate manner.
Special features
The CVD-coated P25/K20 carbide grade provides excellent wear protection and thermal stability for universal use. A point angle of 140° also promotes good centering behavior, minimizes burr formation upon material exit, and ensures smooth drill guidance. The straightforward and accurate attachment to the holder body supports seamless and efficient practical workflows.
