The thing is really fire! It licks off those who do not know the difference between PZ and PH and their sizes. And for those who know: the thing is just belissimo for 1200r just a fairy tale. The best I've had. I licked off three pieces of purchased bits while screwing 12 cm 6mm screws into the dowels, while making a huge effort so as not to slip. I took this set - without effort, stupidly turned the screw so that it broke off, and the hat remained on the bit. The manufacturing precision is so good that the self-tapping screws are held without any magnet simply by fitting to the bit. So impressed that I decided to order a second piece for the country, and at the same time write a review.
