A tool case is a container used for storing and carrying tools. If you're looking for synonyms for this word, there are a few different options to choose from. Firstly, a tool chest is a similar type of storage container for tools, but is generally larger and more heavy-duty than a tool case. Alternately, a tool box or tool bag are other common terms for portable tool storage. Depending on the context, a tool roll might also be used to refer to a more compact storage option consisting of a rolled-up cloth or leather pouch for holding tools. Ultimately, the term you choose will depend on the specific type and size of tools you need to store, as well as your personal preferences for portability and organization.
