Basic blender went bad (motor ran but spindle wasn’t rotating). I wanted to disassemble to see if it could be repaired. Three of the four screws were Phillips head. I had to cut the casing open in order to discover why I couldn’t unscrew the fourth. It was a slotted spanner.
A complete set of security screw bits is ~20 bucks and they’re far more useful than I realized until I acquired them.
I think this was at the bottom of a deep hole, as you can see where the plastic was cut around it. A standard bit and holder wouldn’t fit down that, I don’t think. What the other guys said about a flathead and dremel/grinding wheel is the only option really, but you’d have to be able to ID the little fucker first.
Comon, do some reading:
Do some comprehending. Yes he had to do that. But it was because he was using the wrong bit.
He had to see which bit to use
That can be accomplished non-destructively.
