The term "second-cut" as applied to files indicates?

• A. The second series of teeth cut on the face
• B. The second cut on the edge
• C. The second length of the file
• D. The second type of cut

Answer: (A)

In file terminology, the term second-cut refers to the teeth pattern on the face of the file—the second series of teeth cut into the face. This means there are more teeth per inch than the first-cut, which gives a finer, smoother cut than a file with the earlier set of teeth. It’s about how the teeth are arranged on the main faces of the tool, not about the edge, the length, or a different type of cut. So the phrase specifically identifies the second series of teeth laid out on the face to control how aggressively or finely material is removed.
