[Features]
The screw will always be fastened definitively against the surface.
Because the screw catch is completely locked to the bit by way of an automatic locking function, the projected dimensions of the bit cannot be changed when the impact screwdriver is used.
Screwing can be done with a long screw-driver, even when firmly grasped by a heavy-duty magnet.
[Uses]
For work done involving specific screwing on a flat surface as attached to a rechargeable, electric screwdriver.
