Note that the collet is rotated, not the key. If the key is rotated, the bit will clamp more tightly, so just rotate the collet counterclockwise. 3, the impact Drill Bit can not be taken off: put the impact drill upside down on the ground, press down the drill sleeve at the root of the drill bit with the left hand, hold the drill bit upward with the right hand, and rotate the drill bit around when lifting.
