I didn’t do anything with this screwdriver: I drilled wood (drill diameters 14 mm and length 270 mm) and stainless steel (d. 8), I was very surprised at the power. Despite this, the main task of a screwdriver is to twist various hardware, its small size and adjustment of the torque and speed of rotation made me a very lazy person, when I need to twist something, I take it in my hands, and not a reversible screwdriver as it was before. Its size even plays against it, because I constantly try to put it in the pocket of my overalls and it has already fallen more than once :/ BUT absolutely nothing happened to it. Here only buy a holster for him. It is perfectly cleaned of dust, 5 minutes ago before this photo it was all gray from construction dust. The case is not airtight and this is very sad, because it does not have additional ribs like in the case for the gbh 2-26 dre puncher. Slightly supplemented the case with two PH2 cue balls and a set with a mini-ratchet, which allows you to get by with a minimum set for solving problems. I am 200% satisfied with the purchase, because it also has service manuals and spare parts are very common. I have a lot of experience with various screwdrivers, different price categories, but this one is definitely worth every. About this handsome man, you can safely say - small and bold!
