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. Carbide micro drill bits provide excellent hardness, wear resistance, and heat resistance. They create precise holes with a smooth finish and often eliminate the need for reaming the hole after drilling. Carbide bits require a rigid setup such as a fixed-spindle machine. These bits have spiral flutes that evacuate chips as the bits drill into a workpiece.
