What is the primary use of a prick punch?

The primary use of a prick punch is to make a light mark for hole centers and arcs. This tool is specifically designed to create small indentations on surfaces, which serve as reference points for precision work, such as drilling holes accurately. The light markings help guide the drill bit to the exact spot where the hole is to be made, reducing the risk of misalignment and ensuring a clean and accurate hole.

Using a prick punch is advantageous because it is less likely to damage the workpiece compared to deeper punches. It allows for careful marking without significantly altering the material surface. This is particularly important in aviation maintenance and structural work where precision is crucial for safety and performance.

The other options focus on different uses that do not align with the prick punch's intended function. For instance, making deep indents is more typical of a center punch, measuring angles might involve a protractor or other measuring tools, and connecting points on a surface is often done with a straightedge or chalk line. Therefore, the practicality and precision of the prick punch in marking light references solidify its primary role in prep work before drilling or cutting processes.
