This Nejitori set from Anex will make stuck screws a thing of the past. This set comes with seven screw removal bits and a compatible impact screwdriver body.
Anex screw removal bits work on stripped screws by creating a new groove in the head of the screw.
First, place a compatible bit on the head of your stripped screw and strike it with a hammer until a new groove is cut. Next, put the bit in the body of the impact screwdriver, and align the tip with the newly cut groove. Finally, strike the handle of the impact screwdriver to rotate the screw with extra force.
