Helical-flute drill bits create smaller chips and evacuate them more quickly than standard spiral-flute drill bits. The AlCrN coating on these drill bits 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. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling.
