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. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drills move deeper into the workpiece. These bits have a straight shank that installs into a drill chuck or similar toolholder.
