What is this tool called (heavy duty electrical drill with impact hammer end)

I think it's an impact wrench, Iggy

rattle gun / impact driver

It does not seem to have "impact" functionality.

I looked around and I am convinced that the extension, that was on it, was called "boiler tube roller". I am sure it was used for making boilers and rolling ends for tubes.

Might be a pipe drill. The Iron and steel pipes that carry water at high pressure. Maybe drilling cement or the like sewer / water pipe.

Might be an engine starter for a tractor or the like.

Looking at the output end (a square drive, not a chuck nor a Morse Taper socket) I think that it is not a drill, but rather a wrench. Not sure whether it is just geared down for massive torque, or also includes impact wrench features as well.

And I'll bet that it could kill someone who used it carelessly, just from the massive torque. Get caught between some stationary structure and the handle -- or the screw-in pipe secondary handle.

I would consider it to be a minimum of a two-man tool.

And somewhat interesting that Chicago Pneumatic produced an electric tool like this.

Enjoy, DoN.

It looks to be an old electric impact wrench, Ig. Damn, 3/4 or 1"? The hammer part would be rotary, not axial.

'Course, it also looks a bit like a Chrysler impact _starter_.

Used to drive a roller tube expander to expand the ends of boiler tubes to seal them in the boiler end plate. I've used a similar tool many years ago when doing boiler inspections and retubing them.

There are also air driven ones and for the bigger tubed units hydraulic driven jobbies
