4Pcs 3Mm Dia 4Mm Shank Square Nose End Mill 2 Flutes Carbide CNC Router Bits

The milling cutter is made of tungsten steel (carbide), which has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. These properties extend tool life and keep end mills edge blades, helping to improve cutting accuracy and efficiency. The surface treatment uses AlTiN coating, which has high hardness, making the tool surface resistant to cutting forces and wear, extending service life; secondly, it also has excellent wear resistance and heat resistance, thereby reducing cutting forces , Improve cutting speed and efficiency, so that the tool maintains stable performance; in addition, the AlTiN coating surface has good lubricity, which can reduce the adhesion of chips between the tool and the workpiece, which helps to maintain the smoothness and size of the cutting surface accuracy. The helix angle of this milling cutter is 35 degrees. It provides the best cutting effect and improves chip removal during cutting, thereby improving cutting efficiency and surface quality. This angled design can also reduce the load on cutting and machine tools during processing, improve heat dissipation performance, and extend the service life of cutting tools and equipment. Suitable for cutting carbon steel, malleable cast iron, alloy steel, die steel, etc. For shallow groove machining, side milling and finishing. Use on CNC machining centers, engraving machines and other high-speed CNC machine tools. The longer the length of the tool clamped by the chuck, the better. Combined with the material to be processed, select an appropriate feed rate and cutting speed to obtain better processing accuracy and performance.
