Question

blueprint dimensions and notes: the hole shown in the image is what type of hole? 1 point blind hole stop countersink counter bore

Explanation:

A counter - bore is a cylindrical flat - bottomed hole, often used to accommodate the head of a fastener (like a bolt or screw) so that the head sits flush with or below the surface of the workpiece. In the given blueprint, the hole has a cylindrical section (the larger diameter part) which is characteristic of a counter - bore. A blind hole is just a hole that does not go all the way through the material. A stop is not a standard hole type in this context. A countersink is a conical hole (usually with a 82 - degree or 90 - degree included angle) used for flat - head screws.

Answer:

Counter bore
