  • Monocrystalline Diamond - an overview

    Diamond can be found in the earth in its natural form, or can be man-made. It is the hardest and the sharpest abrasive known. Because of its hardness, it is normally used to work with very hard materials such as tungsten carbide and ceramics. Soft materials should not be lapped with diamond abrasives because of its embedding tendency.
