The mineral known for its hardness and used in drill bits is diamond. As one of the hardest substances on Earth, rated at 10 on the Mohs scale, diamonds can withstand significant wear and pressure. Their exceptional properties make diamonds highly sought after not only for jewelry but also for industrial applications. In drilling and cutting tools, diamond-tipped bits are utilized for their precision and efficiency in penetrating hard materials, such as rock and concrete, thus enhancing productivity in various engineering and construction fields.
