The tool features a three-throw spiral geometry with a rough profile in a \u003cstrong\u003eZ3\u003c\/strong\u003e configuration with a positive design and a front drilling tip of 60°, allowing for stable penetration into the material and efficient chip removal upwards. The dedicated roughing teeth reduce cutting forces and relieve the machine’s drive system.
