Bulk orders will be discounted, please contact us.

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 TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. 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.
