Standard drill bits can be used on some hard metals, but their effectiveness and durability may be limited. Common bits made of high-speed steel (HSS) work well on softer metals like aluminum and mild steel, but when drilling harder metals such as stainless steel or titanium, these bits can dull quickly or break due to increased heat and resistance. For hard metals, specialized drill bits like cobalt or carbide-tipped bits are recommended. These are designed to withstand higher temperatures and maintain sharpness, ensuring cleaner holes and longer tool life. Using the right bit improves efficiency and prevents damage to both the material and the drill bit.

How Do Cobalt Drill Bits Compare To Titanium Drill Bits For Metalworking?

Cobalt drill bits are generally better suited for metalworking than titanium drill bits. Made from a blend of steel and cobalt, they offer superior heat resistance and durability, allowing them to maintain sharpness longer when drilling through hard metals like stainless steel. This makes cobalt bits ideal for heavy-duty and prolonged metalworking tasks. On the other hand, titanium drill bits have a titanium nitride coating that reduces friction and increases surface hardness, enhancing their lifespan. However, once their coating wears off, the underlying steel is more prone to dulling. Therefore, cobalt bits are preferred for tougher metals, while titanium bits are suitable for lighter metalworking jobs.
