For 6 years I twisted and drilled everything they needed . after the fall, the cartridge began to beat a little, and I feel it is the cartridge itself that is a little bit wedged when tightened, but I am a furniture maker, I force him constantly - under the hinges in the array - also to them! Now I want to buy a new screwdriver. But . he will not be able to drill even under the hinges ! It wonβt even . Iβll buy the same one . and a puncher in addition for the same batteries
