What type of tool is best for cutting through harder materials such as titanium?

Cobalt tools are specifically designed for cutting through harder materials like titanium due to their enhanced durability and heat resistance. The cobalt content in these tools provides superior hardness compared to traditional carbon steel tools, allowing them to maintain sharp edges and withstand the high temperatures generated during the cutting process. This strength and longevity make cobalt tools particularly well-suited for machining difficult materials, ensuring that they can effectively penetrate and shape titanium without excessive wear or damage. Other options, such as plastic or woodworking tools, lack the necessary hardness and cutting capabilities for this application, making them unsuitable for working with metals like titanium.
