Cemented Carbide Grades Due to the advanced sintering technology that korloy use, korloy uncoated carbide grades have fine alloy structure which is necessary to get superior quality as a cutting tool. Advantages Consist of,, carbide grades and can be used in all kinds of workpiece. Excellent quality at machining with coolant, due to the great thermal crack resistance of carbide. Due to the special design of carbides, it has fine micro structure and low affinity with workpiece. It has excellent toughness and low cutting load.
