Our tungsten carbide rods are widely used for making endmills,
drills, reamers, and other cutting tools. with good quality and
competitive prices, the rods have been sold to many countries,
mostly in Europe and America.
Our advantage:
- For raw material:
- Constantly excellent WC powder produced by our own factory.
- Spray drying tower and HIP sintering furnace
- Cryogenic treatment to remove the internal stress
- For grinding:
- General h6 rods and h5 or h4 as required
- Straightness 0.01-0.05
- Circularity 0.01-0.05
- General Roughness Ra 0.4, and Ra 0.2 or Ra 0.05 as required.
What we can provide:
Unground/Finished ground Solid carbide rods
Cemented carbide rods with straight coolant holes
Cemented carbide rods with helical coolant holes
Cut-to-length rods
End mills blank with 3/4/5 holes
Our finished ground rods could be h6/h5/h4 as per your
requirements.
