Tap Terminology
Brooke Cutting Tools USA is pleased to provide the following Thread Form Termnology illustration:
In some countries, the name “PLUG” is commonly used to indicate a Bottoming Tap. In America, it is used to indicate a second tap. To avoid confusion with American Terms, the terminology adopted by British Standard 949 1979 as shown above, should be used.
