Question 196General Subjects - QMED

The correct answer is C) Mill. A mill file is the best choice for producing a fine finish on metal. Mill files have a very fine, evenly spaced tooth pattern that leaves a smooth, polished surface on the metal. They are designed for finishing and polishing, unlike coarser files like second cut or float files which are better suited for more aggressive material removal. The other options are not as well-suited for fine finishing. Float files have a very coarse, random tooth pattern better suited for rough shaping. Second cut files have a medium tooth pattern for general purpose material removal. Warding files have a specialized pattern for working in narrow grooves and are not optimized for producing a fine finish on broad metal surfaces.
