I bought this drill 3 years ago, I wanted to use it as a drill-driver, but I immediately knew that there was a slight backlash of the cartridge to the sides, the alignment was off, as a result, screwing a self-tapping screw with a length of more than 4 cm is a problem, it turns from side to side, from -for which the bit constantly flies off the self-tapping screw. The same applies to drills over 5 mm, it hits metal, although thinner ones just bend a little, and drill well. The reverse jammed a few days after the start of the repair. When working, there is a glitch when we press a little to give very low speed, but as a result, the drill starts quickly and slows down.
