Taps and dies used for threading pipe are _______________.

AI Explanation
The correct answer is D) Tapered. Taps and dies used for threading pipe are designed to be tapered in order to create the threaded connection. The tapered shape allows the threads to smoothly engage and seal with the corresponding threads on the pipe. This tapered design is a key feature that enables the effective threading of pipes. The other options are incorrect because: A) Taps and dies are hardened to maintain their sharp cutting edges, B) They are fluted to create the threaded profile, and C) The tapered shape, rather than a straight shape, is necessary for the threading process.
