Steps for Usage:
1. Choose the extractor smaller than the screw diameter and install it on the electric hand drill, turn it counterclockwise to polish a hole on the head of the damaged screw or broken bolt.
2. Then turn the screw extractor over and install it on the electric drill. Still keep the drill reverse and lower speed.
3. Put the threaded end into the damaged screw and rotate it counterclockwise at low speed until the damaged screw is taken out.
Warm Tips :
1. When drilling with a drill end: the speed needs to be set according to different materials, usually the harder the material, the lower the speed of the electric drill;
2. Whether it is drilling or extracting screws, the drill bit must be kept reverse and low speed.
3. When use the take the threaded end:the electric drill needs to be adjusted to counterclockwise and the rotation speed should not be too fast,otherwise it will be easy to slip.
4. It is best to use electric hand drill.
