Tungsten carbide and other carbides are extremely hard materials that can drill in virtually all materials while holding an edge longer than other bits. Due to their brittleness and high cost they are mainly used for drill bit tips, small pieces of hard material fixed or brazed onto the tip of a bit made of less hard metal. E. G. Masonry Drill Bit, Hammer Drill Bit. However, it is becoming common in job shops to use solid carbide bits, and in certain industries, most notably PCB manufacturing, it has been commonplace for some time.
