At present it is known that diamond tool degrades with time as it is normally used at high temperatures. One of the question the authors like to answer in this study is whether thermally induced problems in diamond tool arise as a result of the temperature value itself? They raised the temperature of the diamond tool sample by laser heating it, and describe the physical changes on the diamond tool samples due to the laser heating. The study shows that the temperature in the diamond tool is sufficient to radically alter its physical and chemical properties, resulting in critical fracture.
