Bosch GDR 120-LI Professional 06019F0007

Power, backlighting, ergonomics

I liked its technical features. It can significantly speed up the process of changing wheels as a whole, when swapping winter tires for summer ones and vice versa. It's especially noticeable when my son and I change the tires on 3 cars at once. During construction work, it's definitely preferable for driving in roofing screws. It drives them faster and more powerfully. Most importantly, it doesn't twist the hand holding it. It successfully drives long and thick standard screws. You just need to get used to a slightly different screwing technique. If you don't misalign while screwing, the bit never slips out, doesn't break the cross, and lasts much longer. It's indispensable when you need to unscrew many screws to redo something, and then screw them back in. It does this quickly and easily. It protects the crosses of untempered screws. If the task is to sink the screw heads slightly below the wood surface - with a little practice, this can be done confidently. And very quickly. I'm very satisfied with it, discovering all its advantages gradually, without rushing. It doesn't have an adjustable clutch, but when resistance suddenly increases when screwing, an impact function kicks in during rotation. The greater the resistance, the slower it tightens and the more it rattles. You just need to master this, and you're set. The hand is relaxed and doesn't sharply twist.

The tool is small, especially in length, which makes it possible to get into places where a conventional screwdriver with a cartridge would not fit in principle. And this, by the way, is an important point in my work and it saves a lot of time and nerve cells. At the same time, it has a lot of power and torque, here the impact mechanism helps notably. The important point is not to get too carried away, otherwise you can unscrew the head of the screw or break the thread. There is no tightening torque regulation here and it all depends on the person who performs the tightening. Copes well with screws up to M10 and nuts up to M12 inclusive. This device works with nozzles, bits and drills for a quarter-inch hexagon. The size is common, anything is produced for it, there are no problems with availability or prices. They can also drill well. At the second speed (up to 1300 rpm), drills up to 6-7 mm work perfectly in hard materials, then you need to switch to the first one (up to 400 rpm). The kit includes two batteries, a fast branded charger (really fast in just an hour and a half restores the full capacity) and a suitcase where all this stuff is neatly packed. Two years of a guarantee too on road do not roll.
