The correct choice identifies the specific angle for a countersink cutter designed for deburring purposes. A 100-degree open countersink cutter is commonly used for creating smooth transitions at the edge of holes, particularly for ensuring that fasteners such as rivets and screws can sit flush with or below the surface.

Using a 100-degree angle strikes an effective balance between removing material and preventing over-deburred edges that could compromise the structural integrity of the assembly. This angle allows for efficient material removal while still providing adequate support for the fastener, ultimately contributing to the strength and reliability of the assembly.

In practical applications, using this specific angle is important for meeting industry standards and ensuring compatibility with various components. Other angles, while suitable for specific tasks, may not provide the optimal outcome for every type of fastener or assembly.
