Carbide rods are mainly used for drill bits,end-milling cutters and winches. It can also be used for cutting,stamping and measuring tools. It is used in paper, packaging, printing, non-ferrous metal processing industry. In addition, it is widely used in machining high speed steel cutters, carbide milling cutters ,cemented carbide cutters,NAS cutting tools, aviation cutters,cemented carbide bits, milling cutter core bits, high speed steel, taperd milling cutters, metric milling cutters, micro end milling cutters, hinge pilot, electronic tool, carbide rotary file, cemented carbide tool, etc.
