Doppia sede magnetica

[Features]
· Screws always stop in a consistent position along the surface.
· Automatic locking function completely locks bits to the bit catch so the output dimension doesn't change when using impact drivers.
· The powerful magnet firmly holds even long screws, allowing easy screw-fastening.
[Applications]
· It can be attached to a rechargeable screwdriver for constant screw driving to a flat surface.
