Question 201General Subjects - QMED
70% to passA metal file has become clogged with filings and should be cleaned with a file _______________.
Ascraper
Bcard
Cdressing tool
Doilstone
AI Explanation
The correct answer is B) card. A file card, also known as a file brush, is the proper tool to clean a clogged metal file. The file card has thin, stiff wire bristles that can effectively remove the accumulated metal filings from the grooves of the file, restoring its cutting ability. Using a file scraper, oilstone, or other abrasive tools would not be as effective in thoroughly cleaning the file. The other options are incorrect because: A) a file scraper is used to remove material from the workpiece, not clean the file itself; C) a file dressing tool is used to dress or sharpen the file, not clean it; and D) an oilstone is used to sharpen and hone tools, not clean a file.
