I have a couple of webpages devoted to hole tapping.

Just recently an Australian guy told me that I had my tap styles labeled incorrectly.  
They are:  
-Taper  
-Plug  
-Bottoming.

He said that the “Plug” tap is really called the “intermediate”.  
And that the “Bottoming” tap is really called the “plug”.

I was surprised, since I have been buying and using taps for many years using the taper-plug-bottoming terminology.  
I did some checking and found that in Australia and Britain they DO use those differing terms. I wonder how that happened.  
And then, I wonder what they call the tap styles in the other 200+ countries in the world.
