Tungsten carbide PCB milling cutter is made of high-quality WC fine powders on a precision machine tool through superb technology for applications to process PCB. That is because tungsten carbide PCB milling cutter has advantages of easy cutting, sharp and wear-resistant cutting edge, high hardness, high precision, good surface finish, no burr, sufficient bending resistance and wear resistance, good chip removal and cutting effect. Also, it is not easy to break with durability.

Well, do you know what tungsten carbide is? Tungsten carbide is a fine gray powder in its most basic form, but it can be pressed and formed into shapes through sintering for use in cutting tools, industrial machinery, abrasives, armor-piercing shells and jewelry. Tungsten carbide is approximately twice as stiff as steel, and is double the density of steel - nearly midway between that of lead and gold. It is comparable with corundum (α-Al2O3) in hardness and can only be polished and finished with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels, and compounds.
