Problem with electric.. is cord and the dangers that come with it,, cut an air hose you get a snake that flies around..
cut an electric cord or get it in water.. can be deadly..
problem with cordless.. HEAVY.. and once the battery is dead, you have to wait.. or have multi batteries ..
other problem is they refuse to standardize the battery connection.. even within the same brand..
Unlike say "d"/ "c"/ AA &aaa
So you end up with a bunch of chargers and batteries.. and when that tool craps out and you replace it with the newer model of same brand it won't take the army of batteries you already have. An air tool dies and you buy a new one.. it connects to the same fitting and hose..
Electric be it cord or cordless.. use brushes that many times are not easy to swap.. and oil/greaseless bushings.. and don't last.. full sealed ball bearings are rare until you spend real money.. most are throw away..
Look at many techs tool box.. a large draw or shelf area is nothing but chargers and batteries..
Now if the industry got their head out of their _____ and standardized the connection for tool to battery.. by volts, not make.. it be much better .
Same with home tools,, I have 8 batteries for 16 tools.. and every 4 (bought sets ) have a different battery mounting to tool.. and all are 18volts..
I have 12 flash lights and they all take d batteries..
I have 8 tools that still work but the batteries are dead and no replacements avail..
so.. outside of wiring in a 2 prone connector,, and then making an adapter to hook a battery pack to it.. they are working tools that are useless..
