Diamond is the hardest known material on earth. This is an advanced diamond-based tool material in which tiny diamond crystals are tightly sintered on the cemented carbide alloy base by means of a super high-pressure and -temperature process. When compared with the single-crystal diamond the hardness is slightly lower but PCD is uniform in structure. Additionally the heat resistance performance of singlecrystal diamond can differ according to the crystal quality and orientation. PCD is therefore optimum for cutting of non-ferrous and non-metal materials.
