How to use the screw extractor ?

1. #6 - #10 size needs to be installed in the socket adapter first, then connect it to the expansion position folder (other sizes can be directly connected to the extension bracket).
2. Drill a hole in a broken screw using a drill bit (Dr).
3. Change to use the same size of the extract (Ex) bit.
4. Reverse use of the drill bit, take out the broken drill bit.

Tips:
1. When the surface of the broken screw is smooth, it must be drilled first. Otherwise the drill will slide.
2. Drilling must be vertical and low speed (RPM ≤ 200). Repeated use of this drill bit makes it easier to drill the first hole.
3. It is best to use an electric hand drill and you cannot use the hammer drilling mode! Must be slow when used !
