The tool features a three-flute spiral geometry in a \u003cstrong\u003eZ3R\u003c\/strong\u003e configuration with a positive setup, which guarantees immediate removal of dust and chips upwards while maintaining perfect cleanliness of the bottom edge. The applied TiSiN protective coating significantly reduces friction, prevents overheating of the cutting edges, and prolongs the cutter's lifespan multiple times.
