Designed to tackle the rigidity of granite, these drill bits are typically made from tungsten carbide, a material known for its extreme hardness and wear resistance. The bit's tip is often crafted with a sharp, multifaceted point that helps concentrate the drilling force, reducing skidding and increasing penetration accuracy. Additionally, the flute design is engineered to efficiently remove granite dust from the drill site, preventing clogging and extending the bit's lifespan.

To overcome these obstacles, engineers employ a range of strategiesdrilling through rock. They use specialized drill bits made from materials like tungsten carbide or diamond, which can withstand the harsh conditions. Drilling fluids, often a mixture of water, clay, and chemicals, are used to cool the drill bit, remove cuttings, and stabilize the borehole. Geologists also play a crucial role, studying rock formations and seismic data to guide drilling operations.
