The tool features a three-flute spiral geometry with a roughing profile in a positive configuration \u003cstrong\u003eZ3\u003c\/strong\u003e, ensuring effective chip evacuation upwards and a clean finish on the lower edge of the workpiece. The dedicated roughing teeth effectively divide the material into smaller particles, reducing cutting resistance and alleviating the machine's drive system.
