Carbide Rods

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.

  • Superior raw carbide material with high wear resistance and good corrosion resistance, durable with high service life.
  • Reliable quality with strict quality control after complete inspecting and testing equipment.
  • High-efficiency anti-shake with good rigidity.
  • Precision tolerance to the specified shape and size.
  • Large stock of regular dimension for fast delivery.

Production process

1.Preparing mixture
The ball grinding mill can make all fine and ultra-fine grain size powder uniform.
2.Drying and granulating
We use spraying prilling tower to ensure the purity of the material.
3.Compression Moulding
The carbide rods blanks are pressed by the pressing machine to a uniform density and no defect.
