Ratchet mechanism makes it useful even in tight spaces
The ultra-thin head allows you to get into tight spaces and powerfully turn screws in places where normal screwdrivers cannot. Equipped with a ratchet mechanism that allows you to turn the screw by repeating left and right movements, so there is no need to grasp the grip again.
Offset driver with ultra-thin head
The 21mm ultra-thin head including the bit is effective for driving screws in tight spaces. Since it is possible to apply force in the vertical direction to the screw, it is possible to prevent cam-out (a phenomenon in which the bit rises from the screw hole. One of the causes of screw hole licking).
Smooth bit exchange
The groove of the ultra-short bit prevents the bit from slipping when pulled out. In addition, magnet chucking enables smooth bit replacement.
Set of handle and 5 ultra-short bits
Set of ratchet handle, ultra-short Phillips bits (+1, +2, +2, +3), and ultra-short flat head bit (-6). The same manufacturer's grooved ultra-short bit series (AK-51P) can be used interchangeably as needed.
