The AlTiN coating on these drill bits protects them from wear when drilling hard and abrasive materials and is more resistant to high heat than a TiAlN coating. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. 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. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
