What you call the plug tap we call an intermediate tap, I guess because it's halfway between the taper and the bottoming tap. The bottoming tap also often gets called a plug tap. Dunedin, New Zealand.
Talk about a Roll Tap, an STI Tap, and maybe using a Tapping Head like the Tap-O-Matic versus Rigid Tapping or Power Tapping versus Hand Tapping. Thank you.
I've got a set of "draps" that i use mostly with electrical boxes but they do like to break & their max recommended thickness is no joke. I've had to replace them a few times.
Years ago I was an engineering student working a summer job. The machinist I was working with for some machine parts had a test for me on my first visit. He asked if I needed to call out what side of the plate the hole must be tapped from. Apparently the previous guy thought if you tapped the hole from the other side it would be left handed. My examiner had an aluminum plate with every bolt size he could find, drilled and tapped in increasing size, with the appropriate bolt so that it could be inserted from each side. I passed that test on the first go. I failed many others....
The 2 or 3 flute taps are for power tapping. spiral taps are nice for power tapping because it removes the chips from the top instead of packing the hole full of chips. 4 flute taps should really only be used for had tapping

Most folks don't realize the difference in these taps. Greàt presentation
Thanks for sharing. Another excellent video. In the UK taps are named first taper second taper and plug
You guys are awesome!! Thank you for sharing the type of knowledge that nobody really teaches and stuff we kinda have to learn on our own.
I always pick up a tip or two from you. Thanks for making great videos!

Always learning !!!!! Thanks
"We have most of a set of left hand taps." That made me laugh! So true! Most of a set of anything where I work!
The best one I ever pulled on an apprentice, was telling him that a left-hand thread is cut by cutting the thread from the back of the material😂😂😂

One thing im still wondering is why a person would want more or less flutes on a tap for a particular job ! As in 3 flute over 4 flute and so on !!!
The 2 or 3 flute taps are for power tapping. spiral taps are nice for power tapping because it removes the chips from the top instead of packing the hole full of chips.
4 flute taps should really only be used for had tapping
The less flutes the stronger body is less likely to break off.
An important question is how much time do you spend keeping your shop organized?
A lot & it's never enough. 500-1000 man hours per year
Have you ever used crisco for taping fluid?
What about punch taps?
Missed roll taps and oversize taps for parts getting heat treated.
You forgot form taps! (the best kind of taps)
Black ones, whites one, big ones ,and little ones
