The importance of using a marble drill bit lies in its ability to prevent chipping and cracking, which can significantly degrade the marble's appearance and structural integrity. The unique geometry of these bits, often with a conical or cylindrical shape, allows them to gradually penetrate the stone without exerting excessive pressure on any one point. This gradual process reduces the risk of stress fractures and ensures a clean hole.
