Tungsten Carbide Blank Solid Rods for milling tools
Our rods have different grade and right to use on different
application; Specially we are produce the Nano Grain carbide
(Grain＜0.2µm); Our rods are with high hardness and wear/corrosion
resistance, all products with stable quality;
- 100% raw material;
- Hip sintered, high hardness, high wear resistance;
l Dimension: diameter from 2-48mm, length up to 330mm;
l with one coolant hole or helix holes rods and blind hole rod;
l Ground(tolerance with h6/h5/h4) and unground;
