Product Description
Diamond drill bits—also known as diamond core bits, diamond core drills, or diamond-tipped drill bits—are precision drilling tools designed for high-precision machining of materials. They are commonly referred to as glass or tile drill bits, but their applications extend far beyond these names.
Manufactured using industrial diamond abrasives, these drill bits are widely used for drilling glass, modern ceramics, porcelain, ceramic and porcelain tiles, limestone, slate, marble, granite, soft stone, and fiberglass. In addition, diamond drill bits are increasingly used in optical material processing, for example, for drilling and shaping optical glass, quartz components, and transparent crystalline materials, where high dimensional accuracy, smooth bore walls, and minimal chipping are critical requirements.
