The essential usage of fixed length carbide rods are for carbide endmills, according to material hardnessto be machined,carbide endmils could be devied to HRC45,HRC55,HRC60,etc. The carbide rods blanks material are choosed according to the working environment of carbide endmill, Tougher carbide rods for tougher material.
By the way,tungsten carbide micro drills is one of the most importanct carbide cutting tools in PCD industry with high efficiency.
