Cutting tools

Definition

Cutting tools are specialized instruments used to remove material from a workpiece through mechanical means, typically during machining processes. They play a critical role in various applications, including metalworking and manufacturing, where precision and efficiency are paramount. The effectiveness of cutting tools can be enhanced by materials such as boron nitride and boron carbide, which provide superior hardness and wear resistance.
