First prepare the tool hand drill, proper bit and extractor.
Make a hole in the center of the section of the wire with the sharp object first, then use the electric drill (positive and negative rotation) to bring the drill hole (note: rely on the middle drill, do not make the broken drill too thin), hit the wire extractor can screw on it.
Because the wire extractor is reverse wire and the screw is normal wire, the tighter the screw extractor is, the drive the broken wire will come out.Specifications:
