Bosch GSR120-Li 12V hand drill from a netizen
The screws had been removed when it arrived, and the motor and switch were severely corroded
It did not rotate when plugged in. After opening and cleaning, it was found that the motor was stuck. After spraying lubricant, it could rotate normally
The gearbox lacked lubrication
It was a pity that the chuck was not disassembled despite all efforts. In order to retain the original chuck, no violent disassembly was performed
Finally, the function was fully restored. The small electric drill is easy to carry, and the torque and speed are basically sufficient.
