Are Cobalt Or Titanium-Coated Step Drill Bits Better For Metal Drilling?

Cobalt and titanium-coated step drill bits both offer advantages for metal drilling, but their suitability depends on the specific task. Cobalt bits are made from an alloy that provides excellent heat resistance and durability, making them ideal for drilling into tough, hardened metals. They maintain sharpness longer and can handle heavy-duty use without significant wear. On the other hand, titanium-coated bits have a surface layer that reduces friction and increases bit life, but the coating can wear off over time. Titanium-coated step drill bits work well for lighter to moderate metal drilling tasks, offering smoother cutting and extended bit lifespan compared to standard bits. For heavy, frequent metal drilling, cobalt bits are generally the better choice.
