China 111AAA-Micron Grain-Sub Micron Grain Tungsten Cemented Carbide Rods for End Mills Drill Bits R

The Introduction of the Carbide Rods

The Tungsten Carbide Rods, Blanks are made by Extrusion from the highest purity of Materials and Sinter Hiped. Be of very high quality and tool peroformances, the grade for Cutting tools are usually in Sub-micron Grain and Ultra-fine Grain. As demand,the other grade can be custom-made.
They are ideal materials for the Solid rotoary Cutting tools, like Solid Carbide Endmill, Drills, Remaers, Taps.etc.
Usually, the carbide rods are in sintered conditions, but we can arrange the grinding process as per the clients specific demand. Our grinding are done by the imported Centerless grinding Machines, we can meet the precision demand of our cleints from both Europe and American, usually, we control them in h6 finsihing, as demand, we can control it be h5, h4, h7.

We can even grind the Cemented carbide rods even in 0.3 mm diameter if you have.
