It is impossible to use as a magnet catch because the attraction force of the tip magnet is too weak. Even if you try to take a screw in a narrow place with a magnet, the attraction force is weak and it will not be used. Moreover, the tip part gradually peeled off by use. Even if you try to tighten the screw while catching it with a magnet, the magnet will be too weak and the screw can not be held and will fall off immediately. The screw dropped off and it did not become a job at all, and it changed to a driver of another company without being numb. I feel like I lost it.
