I have 2 identical 18v cordless drill/drivers and I usually have both on hand (one w/ drill and one w/ driver for my (rough) carpentry projects like putting up a privacy fence or hanging gutters, installing garage doors, assembling Harbor Freight trailers etc. And I've got air tools -- mostly for removing car wheels.
Lol but none of them go near my bikes. lol The yield points come too quickly sometimes. I got pretty good w/ screw extractors in my youth. Haven't had to break them out for awhile. lol
