I am going to refer to cordless drills, as corded drills (at least the professional ones ive been using, are solid enough to rather damage an idiot user, and unlikely to suffer any damage from misuse).
But cordless drills are very delicate and even the best drill out there can easily be damaged by an idiot, who:
- uses the drill with the speed setting stuck in between gears/modes
- rides the same battery even if its obviously very low on power already
- pushes the bit way too hard into wood or concrete, when it should be known that a sharp bit doesnt need anything but a very slight push to bite
- doesnt stop the drill when the clutch cuts in
- doesnt stop the drill when the bit gets stuck, burning the motor this way (easy to achieve with auger and forstner bits which are very aggressive and require a very powerful drill)
- generally uses the drill for applications that require a more powerful drill
- even hurts himself when the drill twists the handle due to the bit getting stuck, due to immense torque (anything over 60Nm can break your wrists)
to elliminate all these issues, you`d need a very complicated machine with incredibly advanced electronics, which would end up costing more than your average idiot could afford anyway. And professionals already have their trusted brands and model lines they invest in.
To conclude, in my oppinion, the idiot proof cordless drill already exists, its the ones you can find in any warehouse for prices ranging between 19.99 and 99.99. Its idiot proof because if you break it, you can just get another one under warranty. By the time your warranty expires, you`ll either get to know one or two things about drills and thus not being an idiot anymore, or you can develop into being a stubborn idiot that just knows he needs a more powerful drill, churns out 200 for it and fries it in a week.
