Polished Cemented Tungsten Carbide Rod H6 Finished Ground K20 HRA 92.8

H6 Finished Ground K20 Tungsten Cabide Rods Polished Cemented Rods Product Details: Application: End mill/ Drills finished ground blanks Diameter: Ø1.6- Ø40mm Length: 330mm or cut-to-length Circularity: 2μm-5μm Straitness: 0.04-0.07 Surface roughness: Ra 0.02- Ra 0.4 Solid finished ground carbide rods are usually used for making endmills, and drills. Ouqi can provide precision ground rods in which the circularity and straightness could be 0.02mm and surface roughness can be Ra 0.02. With advanced equipment, the capacity could be 10,000kgs per month for the finished ground rods.
