These drill bits come in sizes expressed in fractional inches. They 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. This listing is for each.
