What is used in metal-cutting prints to represent information such as hole diameter and depth?

The use of symbols in metal-cutting prints is essential for conveying specific information in a concise and standardized manner. Symbols can represent various features such as hole diameters, depths, and other machining specifications, allowing for quick and accurate interpretation by machinists and engineers. This symbolic language minimizes ambiguity and enhances communication between parties involved in the manufacturing process, ensuring that everyone understands the precise requirements of the design.

Other choices may seem relevant but do not serve this specific function effectively. Graphs are generally used for representing data trends rather than detailed specifications in technical drawings. Charts might be used for summarizing information but lack the precision needed in a technical drawing context. Illustrations can provide visual guidance or examples but do not focus on the standardized representation of measurements like symbols do. Therefore, symbols are the most appropriate and widely used means to convey technical information in metal-cutting prints.
