What tool is used to inspect the chamfer after it has been completed?

The countersink gauge is specifically designed for inspecting chamfered edges or angled surfaces after they have been completed. This tool allows for the accurate measurement of the angle and depth of the chamfer, ensuring it meets the necessary specifications and standards for aerospace components. It typically has a slotted design that can fit over the chamfer, enabling the inspector to assess whether the geometry is correct and consistent.

While other tools, like calipers, micrometers, and depth gauges, have their own measuring applications, they do not provide the specialized accuracy required for evaluating the specific features of a chamfer. A caliper might measure width or depth, but not the angle or the precise characteristics of the chamfer profile. Similarly, a micrometer could measure thin dimensions, but it’s not suitable for checking specific chamfer angles. A depth gauge serves the purpose of measuring the depth of holes or recesses but wouldn’t effectively assess a chamfer's angle or overall profile. Thus, the countersink gauge is the ideal tool for this particular inspection.
