• Multi-layer nano-coating: The introduction of nano-materials into the coating can significantly improve the high temperature resistance and oxidation resistance of the material, further improve the hardness and wear resistance of the coating, and maintain high toughness.
• Efficient roughening: the wave edge band prevents vibration and broken blades. Multiple rows of large spiral chip flutes effectively prevent tool sticking and improve efficiency.
• Sandblasting passivation treatment is more durable: a passivation film with dense coverage and good performance is formed on the surface and will remove all kinds of dirt, increase oxidation resistance and extend the service life of the tool.
• Applicable materials: stainless steel, alloy steel, mold steel, No. 45 steel and other rigid materials.
• Applicable machines: CNC machining centers, engraving machines, engraving machines and other high-speed equipment.
