Yes sorry about the FIL I hate all this BS ( opps bull butter) with acronyms.. I had to look up what EDC was regarding a knife. Every Day Carry...

lol yeah, the younger texty generation keeps coming up with acronyms for everything
EDC got me too when I first heard it
I thought maybe it was a special purpose item or brand
nope, generic as can be

My guess was a tapping head.. Looks kind of like an armature..

markT and WSnyder are correct. Tapping unit
