Tips for observing the drill cutting edge

With metal products, there is a big difference between the overexposed areas and the shadowed areas, so special care is required for polished and plated surfaces.
Furthermore, it becomes even more difficult if there are irregularities or R surfaces.

As an example, we checked the difference in appearance of the tip of a drill (which has an uneven, rounded surface) by changing (1) lighting, (2) camera, (3) background color, and (4) options. .
