Wikipedia
Counterbore
A counterbore (symbol: ⌴) is a cylindrical flat-bottomed hole that enlarges another coaxial hole, or the tool used to create that feature. A counterbore hole is typically used when a fastener, such as a socket head cap screw or fillister head screw, is required to sit flush with or below the level of a workpiece's surface. Whereas a counterbore is a flat-bottomed enlargement of a smaller coaxial hole, a countersink is a conical enlargement of such. A spotface often takes the form of a very shallow counterbore. As mentioned above, the cutters that produce counterbores are often also called counterbores; sometimes, to avoid ambiguity, the term counterbore cutter is used instead. The symbol is Unicode character U+2334 ⌴ COUNTERBORE.

counterbore
A counterbore is a cylindrical flat-bottomed hole that enlarges another hole. It is typically used when a fastener, such as a bolt, is required to sit flush with or below the level of a surface. This tool serves the purpose of concealing the head of the bolt. The counterbore creates a consistent diameter for the head of the fastener, providing a tidy finish. On a broader aspect, it's a specific kind of drilling or boring technique.
