How do you remove the cutter head on the screwdriver?
Use the hand to screw the head of a small round set down, and then broach the head out, and very simple, if the rust can not pull out, you can drop a drop of lubricating oil, and so on for a while, then pull out.
Some screwdriver can unload, some can not, can unload to the outside a pull out can, is by magnetic force even, not this kind of words can't change tool head
The swivel head is lowered down, and so does the top
