China Cemented Carbide Round Bars with Weldon from China Manufacture Manufacturers, Factories
Product Description
The Introduction of Carbide Rods
The tungsten solid carbide rods are press-molded through specialized molding or extrusion methods.
Sintered in a low-pressure sintering integrated furnace, maximizing overall mechanical performance and durability.
Rough tungsten-cobalt carbide round bars, or outer diameters, can be refined and polished to standard tolerances (h5, h6, -0.005, etc.) with custom end chamfer processing available.
Ideal for machining general steel, cast iron, stainless steel, heat-resistant steel, nickel-base, and titanium alloys. Recommended for twist drills, end mills, taps, and gun drills.
