Drill - 1.4mm Solid T/Carbide(732-1.4)

Solid Tungsten Carbide Drill. Tungsten Carbide and other carbides are extremely hard materials that can drill in virtually all work piece materials while holding an edge longer than other bits. Due to their high cost and brittleness, they are often used only in tipped tools, in which small pieces are screwed or brazed onto the tip of the bit. However, it is becoming common in job shops to use solid carbide drills, and in certain industries, most notably PCB drills, it has been commonplace for a long time.
