Hello JR,
I guess so.... we always called the tool a "tap" and when using the tool we always called it "tapping" a hole.
Maybe it's a regional thing? I did look up Tap, Tap and Die, and finally "gun tap", it appeared to be the same device. Wilkipedia has a listing under "Tap", so ...?
Cheers,
Hammer

I apologize if my word play was lost on the SR crowd.
In thread cutting taps there are 4 flute and 2 flute designs. The flutes are the open parts where the metal chips escape. "Gun" taps (the two flute type) are designed to cut the thread in one continuous pass, in till the driver bottoms, then out again. The 4 flute taps are commonly used when tapping holes by hand where you advance less than a full turn than back up to break the chip, then advance again...
One of my early summer jobs (40+ years ago) was in a machine shop and I tapped a lot of holes. When you're tapping holes 8 hours a day, you use the right (power) tool for the job.
The machine shop was in NY state so I doubt this is regional slang.
4 flute "hand" tap
2 flute "gun" tap
and much to far to go for a little humor, so I'll inform instead...
JR
