The cutting action of a diamond bit is achieved by scraping away the rock. The diamonds are set in a specially designed pattern and bonded into a matrix material set on a steel body. Despite its high wear resistance, the diamond is sensitive to shock and drill string vibration, and therefore, great care must be taken when running a diamond bit.
