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 an AlCrN coating that protects them from wear during dry, high-speed machining applications. It is harder, resists cracking and oxidization better, and performs better in high-feed applications than a TiAlN coating. It also resists high heat better than an AlTiN coating. The bits have spiral flutes that evacuate chips as the bits drill into a workpiece, and they have a straight shank that installs into a drill chuck or similar toolholder.
