The tool features a uniform spiral geometry in configuration \u003cb\u003eZ1\u003c\/b\u003e with a positive angle, which facilitates efficient chip removal upwards. The use of high-grade micro-grain carbide ensures high resistance to abrasive wear and significantly extends the cutting edge's durability.
