Popular articles about the handheld power tools used on EVA by astronauts usually focus substantially on how much specialized engineering goes into making these tools. And there definitely are a lot of engineering concerns to make them reliable and efficient in space.
But I wonder whether cheaply-modified commodity power tools could be made to work practically at all, or if they would just be a complete no-sell.
The proposed modifications would include:
Start with an ordinary commodity drill/driver or impact driver that uses a lithium-ion battery and a brushless motor (the latter have become common and inexpensive in the last couple of years)
Regrease everything that is greased with krytox or other high vacuum lubricant
Wrap the tool in shiny thermal-control tape (like the actual NASA Pistol Grip Tool is), possibly after adding some insulation
Get some small vapor heat pipes, add some heat sinks to them, and stick the other ends of them to the stator of the motor and to the power controller with the most thermally-conductive metal-filled epoxy you can find
Package with a scrap of space blanket and a hot pack to warm up the battery in case you're in the shade.
Obviously this bodged monstrosity would never be qualified for any modern space-program flight. But I am curious whether anything is noticeably missing, whether this would work well enough to be worth not just using a screwdriver, or whether it just would completely fail due to thermal or vacuum effects.
