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