Squaring and finishing the uneven surface around a hole is called spot facing. The operation just produces a flat surface enough for a washer to fit flat unlike a hole in case of counter boring.

Sir, I think the answer of this question is counterboring. Because when the end of the hole is conical i.e. countersinking and when the end of the hole is square i.e counterboring.
