Craftsman Kromedge Poly-Tap

[Yadda]

Put this under tools I didn’t know existed.  I picked this up in the estate sale lot this past weekend.  According to sources on the web it is used to tap or chase threads in electrical boxes.  Used by electricians.  Klein makes a similar version.  This one is out of production.

I used to use the Klein tapping tool years ago. Sometimes the threaded holes in metal boxes are malformed and have to be tapped out. There are also times where we have to create a threaded hole for a screw, primarily ground screws. All of the tapping tools I have used are for 6-32, 8-32, and 10-32 screws. If you look at a picture of the Klein tool, you may notice that the tapper is replaceable. That is due to the tapper being brittle and easy to break. Nowadays, I use thread tapping drill bits.

I bet my dad still has a couple of intact tapping tools in amongst his collection of tools.

I use the Klein all the time still.

I try to stay away from power tools on boxes but I am sure in the minority there too.
