These drill bits meet National Aerospace Specification (NAS) 907 Type J for drill bits used in aircraft repair and production. 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. They also have spiral flutes that evacuate chips as the bits drill into a workpiece.
