I looked at a set of them last year, pricey. Seems easy enough to make from tool steel and then harden. Also saw a youtube video of a HVAC tech that drilled a hole in the side of a suction manifold, and used this tool to make a raised surface, in this case he was installing a thermostatic expansion valve reference pressure tube, on a large system. This produced a stronger hole to braze the tube into.

I don't think so, as you need a soft drawn copper for this to work, i.e. it will not work in hard drawn copper. In steel, it will spin and make heat. The other issue is the EMT connectors provide ground bonding between pieces, if you were to swage them, you would have to braze the pieces, and the zinc oxide that is part of the galvanized plating is not good to breath in.
I did not articulate that very well, but that was my point. I can't think of a non electrical use where swaging the pieces together would be of value, but mlochala may have some application.
I have the old style swaging tool where you use your flaring block to hold the copper tube, then wack the swage tool with a hammer. The benefit of this tool is it appears to burnish the copper. Where I've seen them used is on youtube videos where the HVAC tech is replacing compressors or filter dryers, and fitting in the tubing stubs to the existing system without using couplings.
