Which of the following statements is true regarding carbide and cobalt tools?

Carbide and cobalt tools are known for their exceptional hardness and wear resistance, making them well-suited for cutting harder materials, such as titanium and composites. Carbide tools contain elements like tungsten carbide, providing superior cutting performance and longevity compared to standard high-speed steel tools. The ability of these tools to maintain their cutting edge under high temperatures further enhances their ability to machine hard materials effectively. This characteristic enables aerospace mechanics to achieve precise cuts in demanding manufacturing processes, where both strength and accuracy are critical.

The other statements do not accurately reflect the properties and applications of carbide and cobalt tools. While these tools are not exclusively for soft materials, they excel in cutting a broad range of materials, especially those that are harder and more challenging to machine, which solidifies option B as the correct statement.
