The TiAlN/AlCrN multilayer coating on these drill bits protects the bits from wear and extends their life when drilling steel and cast iron. As one layer of the coating wears down, a new layer is exposed. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel or cobalt bits and require a rigid setup such as a drill press. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
