Punch Pin Made by Tungsten Carbide provided by us, is well-known throughout the country and is available in a number of sizes. The original features of tungsten carbide, such as its hardness comparable to diamond, and the toughness of cobalt as a binder, persist due to the particular procedure for creating such alloys. Punch Pin Made by Tungsten Carbide is mostly used to finalize the screw head and recess shape. This pin has a strong wear resistance and tensile modulus, allowing for long-term work in any degree of deformation while maintaining the same standard size. This pin is very effective to use.
