Collection: Diamond Drill Bit

Diamond drill bit is a precision cutting tool designed for drilling holes in hard, brittle, or abrasive materials such as glass, ceramics, stone, and concrete. Unlike conventional drill bits that use sharp metal edges, diamond bits feature a cutting edge embedded with industrial-grade diamond particles, either bonded in a metal matrix or electroplated onto the tip. This allows for smooth, clean, and precise drilling without cracking or chipping delicate materials. Available in various sizes and core designs (such as hollow-core for masonry), diamond drill bits are commonly used in construction, plumbing, and crafts. They can be used with water cooling to reduce heat and extend lifespan, making them ideal for both professional and DIY applications.
