Fast-spiral-flute drill bits evacuate chips more quickly than standard spiral-flute drill bits. The WXL coating on these drill bits protects them from wear and is designed for drilling nonferrous metals and steels with a Rockwell hardness of up to 50 HRC. It is harder and has a higher oxidation temperature than a TiAlN coating.
