The screw removal kit is made of 4341 high speed steel, with high hardness, hard texture and more durable. It can provide more extraction possibilities for broken screws or bolts of different sizes (2-12mm), and can be used for irregular and serrated irregular cutting.
The quick extension holder of a small screw extractor set has a magnetic attraction and automatic locking that assists you to hold the extractor more firmly and protect it from shaking which saves your time and energy. The magnetic bit holder of the screw extraction tool with a customizable collar of typeset can assist you to absorb a high-torque of new impact drivers.
This screw bolt extractor set is only compatible with electric drills. When removing damaged screws, electric hand drills are preferred to hammer drills. Avoid using the hammer drill mode! It must be turned in reverse and at low speed.
1. First, install the size of #6-#10 in the socket adapter, and then install it on the expansion bit holder. Other dimensions are directly installed into the quick extension bit holder/ bit holder.
2. Choose a bit smaller than the damaged screw. Install it on the electric hand drill and start to drill downward to form a clean hole.
3. Change to use extract bits of the same size.
4. Use the drill in reverse direction, the speed of the drill should be less than 200 rpm, and then remove the damaged screw counterclockwise until the screw is loosened.
