Wire-size drill bits come in standard sizes that correspond to American Wire Gauge (AWG) sizes. The larger the wire size, the smaller the bit. These drill bits have a bright finish that is not affected when the bits' cutting edges are resharpened, and they have spiral flutes that evacuate chips as the bits drill into a workpiece. The bits' straight shank installs into a drill chuck or similar toolholder.
