Product Description
Carbide rods are mainly used for drills, end mills, and reamer. It can also be used for cutting, stamping and measuring tools. It is used in the paper, packaging, printing, and non-ferrous metal processing industries. In addition, it is also widely used in the processing of high speed steel tools, carbide milling cutters, carbide tools, NAS cutting tools, aviation tools, carbide drills, milling core drills, high speed steel, taper milling cutters, metric Milling cutters, micro end milling cutters, hinge pilots, electronic cutters, step drills, metal cutting saws, double guaranteed diamonds, guns, angle cutters, carbide rotating jaws, carbide tools, etc.
Tungsten carbide double helix holes rod is a kind of rod with double helix holes, the general helix angle are 15°, 40°, 45°and 60°. Tungsten carbide rods with two holes are mainly used for PCB micro drills, electrode rod of optical communications industry, drill bits of machining industry, drill shank, wear precision parts and so on.
