I think people who use power drills with those screwdriver “drill bits” are just plain lazy.
I had a new ceiling fan installed yesterday, and the installation guy came over with a power drill fitted with the Phillips screwdriver bit to do his job, and he used it on everything. The fan came with the blades and motor hub separately, so some assembly was required. Just have a look at the result.
Here’s a view from the top. If not for the fact that this screw has a groove into which you can insert a flathead screwdriver, you probably won’t be able to remove this at all.
I actually needed to unscrew the bottom cover (which they term the canopy) to check if there’s a serial number printed on the motor hub. I’ve tried 3 different Phillips screwdriver and none of them can grip the screw properly.
The thing about using a power drill is it’s powerful – it really jams the screw in there tight. But if you abuse or misuse it like this, you will probably have a hard time trying to remove the screws, and when you do, you have to find a replacement screw.
So, why couldn’t the guy just have used a regular Phillips screwdriver? I think he was just fucking lazy. How would you feel if your factory-assembled products came with stripped screws like that?
