How to Use the Screw Extractor?
Step 1: #6-#10 size of drills needs to be installed in the socket adapter firstly, then attach it to the extension bit holder. (The other sizes (#1-#5) can be attached to the extension bit holder directly)
Step 2: Use the drill (Dr) bit to drill a hole in broken screws. (Note: drill deeper will easier to take out)
Step 3: Change to use the extract (Ex) bit with the same size.
Step 4: Reverse use the drill and take out the broken bit.
Warm Tips:
1. It is recommended to use electric hand drill instead of the hammer drill.
2. Must drill a hole first when the damaged screw surface is smooth. Otherwise the drill bit will slip.
3. When stripping the damaged screw, Must use it vertically in reverse and low speed (RPM≤200) throughout the whole process. Or you’ll get hurt.
