The term "bastard" when applied to files indicates?

• A. Coarseness of cut
• B. Length
• C. Brand
• D. Type of metal

Answer: (A)

In machining, file cuts describe how coarse the teeth are and how aggressively the file removes material. The term bastard identifies a specific coarseness level: it sits between the rough cut and the second cut. That means the teeth are larger and more spaced than a finer cut, so material is removed quickly, but it’s not as coarse as a rough file. You’d use a bastard file when you need to shape or remove stock efficiently while still leaving a more even finish than a very rough cut would. The other options aren’t about the teeth layout or cutting action. Length doesn’t define how coarse the teeth are, brand is just who made the file, and the metal type doesn’t determine the cut designation.
