(The blade diameter above 5mm is the same as the shank diameter). Please see the picture for specific details. TISIN coating on the blade: TsN coating can directly perform rough machining to fine machining on heat-treated materials below 45°, reducing the number of tool changes, improving machine tool utilization, and saving manufacturing time. 0.6um micro-grain tungsten steel cemented carbide: adopts micro-grain tungsten steel base material, which has higher wear resistance and strength, and belongs to the exclusive milling cutter for high-hardness high-speed cutting applications. Fully sharpened edge: The cutting is sharp, wear-resistant and durable, which provides a strong guarantee for the service life of the milling cutter and a longer service life.Applicable materials: stainless steel, cast iron, copper, graphite, plastic, composite materials, etc. Please according to your choice, thank you!
