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