Working with tough materials like granite, marble, and porcelain often leaves professionals and DIYers with a common headache: jagged, uneven, or improperly sized holes. Traditional drill bits frequently cause chipping around the edges of expensive tiles, and once a hole is drilled, adjusting its size or smoothing the internal rim can be nearly impossible without the right specialized equipment. This often results in wasted materials and a finish that looks amateur at best.
