Which tool would likely not be used in the deburring process?

In the deburring process, the primary goal is to remove sharp edges or rough spots from the surfaces of materials, which is crucial for ensuring the parts fit correctly and safely without causing injury during handling or assembly. A wooden dowel is typically not a suitable tool for this purpose because it lacks the abrasive quality necessary to effectively remove burrs or smooth out edges.

In contrast, tools like flat files, sandpaper, and hand grinders are specifically designed to achieve the desired effect of smoothening surfaces. A flat file provides a controlled way to scrape away material, sandpaper can be used for finer finishes, and a hand grinder allows for more aggressive material removal. Each of these tools serves an essential role in deburring, demonstrating their appropriateness for the task. The wooden dowel, however, lacks the required properties to perform effectively in this context. Thus, it would not be chosen for the deburring process.
