Which description fits a blind hole?

A blind hole is defined as a hole that does not go all the way through the material but instead ends before exiting the workpiece. This characteristic differentiates it from other types of holes, such as through holes, which penetrate entirely through the object. Blind holes are often used in applications where a fastener or a specific feature requires the hole to be closed on one end, allowing for secure anchoring or accommodating certain components without compromising the integrity of the surface on the opposite side.

This attribute is essential in various engineering applications, including manufacturing and assembly processes, where the physical properties of the part must be maintained. In contrast, the other options describe qualities not associated with blind holes, such as completely penetrating holes, variations in diameter, or decorative purposes, none of which pertain to the definition of a blind hole.
