The term double-cut describes the file feature of what?

• A. Courses of teeth
• B. Teeth arrangement around circumference
• C. Length
• D. Material type

Answer: (A)

Double-cut describes the teeth pattern on the file. In files, the way the teeth are ground into the surface is called the cut, and a double-cut file has two sets of teeth that cross each other. This cross-cut arrangement creates a more aggressive cutting action, removing material faster and leaving a rougher finish than a single-cut file. That pattern of teeth—the courses of teeth—is what the term is signaling, not the file’s length, the material it’s made from, or any circular arrangement.
