How to use the screw extractor?
1. The size of #6-#10 needs to be installed in the socket adapter first and then connected to the expansion clamp (other sizes can be directly connected to the expansion bracket).
2. Drill holes in broken screws using a drill (DR) bit.
3. Change to use extraction (Ex) bits of the same size.
4. Use the bit in reverse and take out the broken bit.
When the surface of the broken screw is smooth, holes must be drilled first, otherwise the bit will slide.
When drilling, it must be vertical and low speed (RPM ≤ 200). Used repeatedly of this bit, the first hole drilled is easier to be taken out.
It is better to use electric hand drill instead of hammering drilling mode. Use at low speed!
