Carbide rod is a tungsten steel round bar, also known as tungsten steel bar. In short, it is tungsten steel round bar or cemented carbide round bar. Cemented carbide is a composite material composed of refractory metal compound (hard phase) and bonding metal (bonding phase) produced by powder metallurgy.
Carbide rods is mainly used for drill, end mills. It can also be used for cutting, stamping and measuring tools. It is used in papermaking, packaging, printing, non-ferrous metal processing industries.
In addition, it is also widely used for machining high-speed steel cutting tools, carbide milling cutters, carbide cutters, NAS cutting tools, aviation cutters, carbide drills, milling cutters, coring drills, high-speed steel, taperd milling cutters, metric milling cutters, micro end milling cutters, hinge pilot, electronic cutters, ladder drills, metal cutting saws, double guaranteed diamond drills, gun-barrel, angle milling cutters, Cemented carbide rotary file, cemented carbide cutting tool, etc.
