Tap drill size is the drill size that would leave adequate material in the hole for the tap to cut a thread.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The tap drill size is indeed the drill size that ensures there is enough material in the hole for the tap to create a thread. This is important because if the hole is too small, the tap may not be able to properly cut the thread, resulting in a weak or ineffective connection. On the other hand, if the hole is too large, there may not be enough material for the tap to grip onto, again leading to a poor thread. Therefore, it is crucial to use the correct tap drill size to achieve a successful threaded hole.Rate this question:
