The first picture looks like a Harborfreight drill. What destroys right angle drills is using a hole saw, running it on the hi RPM setting, and having it grab. Severe grabbing is usually more of a problem cutting for toilet rough ins. If it has a cheap gear box, it will strip out gears - no telling how many times before the gears go.
I wouldn't think twice about using one of those for electrical and smaller holes (up to 3-4 inch) in solid wood.
