What are chisels primarily used for in automotive work?

Chisels are primarily used in automotive work for cutting off damaged parts or badly rusted nuts, bolts, and rivet heads. When nuts, bolts, or other fasteners have become corroded or stripped, traditional removal methods may prove ineffective. In such situations, a chisel can be employed to cut through the metal, freeing the damaged part for further repair or replacement.

Chisels come in various shapes and sizes, which allows them to be effective in confined spaces or when dealing with fasteners that are not accessible by standard tools. Their sharp, hardened edges enable them to create precise cuts, ensuring clean breaks that minimize damage to surrounding components.

In contrast, the other options do not accurately represent the primary functions of chisels in automotive work. While chisels can theoretically perform other cutting or shaping tasks, their primary application is focused on removing obstructive or damaged parts, which is crucial for maintaining vehicle integrity and functionality.
