This milling cutter set is made of high-quality tungsten carbide material with stable performance and long service life. It uses ultra-fine grain tungsten carbide for high wear resistance, strength, and suitability for high-speed cutting applications. This carbide end mill set offers high toughness, excellent wear resistance, high hardness, and efficient high-speed cutting to help save time. The blades feature a protective coating, enabling precise finishing during high-speed roughing of hot materials and reducing the frequency of tool changes. It is suitable for machining aluminum, copper, carbon steel, die steel, alloy steel, and cast iron.
