I bought a Milwaukee M12 3/8 angled driver for the workshop, and, to be honest I'm not at all impressed with the torque it's able to generate.
Anything over 40 lb/ft and it stalls, requiring me to break the nut by hand.
Are you confident that the 12v tools will be sufficient for what you need ?
Maybe the Fuel range would have been better for workshop use, but I'm disappointed with the single Milwaukee tool we have so far.
In comparison, we have a DeWalt 899 18v impact gun, which is an absolute beast.
