Remanufactured Porter Cable 20v torque driver / impact combo, charger 2 batteries
from NEWEGG 5-6 yrs ago, 100bucks . Solid as a rock ! same 2 batteries still going now
metal stud framing all day,, 20g, 18g,even 16g with the impact
I shove the 20v PC lithium battery into the ryobi 18v 6" skillsaw ,, and it sings now,
JUST LINE UP THE PINS +/- . velcro strap it on*
I use the adjustable torque driver on lite duty stuff (MOPEDS),, and as a drill,
