Review on DEWALT 21 Pack Black Oxide Twist by Amanda Castillo

I bought such a set of drills in Castorama. 1100 rubles for 10 drills. Moreover, next to the set, the same drills were sold separately. A 10mm drill, for example, cost 400 rubles. So the benefit of buying the whole set was obvious. The transparent lid of the set is very flimsy, but hasn't broken yet. Although, even if it breaks, nothing will fall out anywhere. Drills 1-5 mm are quite ordinary in appearance. Except for the gold oxide coating that protects the drill from overheating. But even "regular" drills drill just fine. Fast and clear. Apparently sharpening Split Point makes itself felt. Starting from 5 mm, the drill shank does not have a round section, but a trihedral one. To prevent scrolling in the chuck. In addition, the Pilot point technology is used on the drill tip, which reduces the contact patch at the start of drilling and prevents the drill from moving from a given point. Excellent drills, but you need to hold the drill firmly, because due to the speed of drilling, the drill can warp and it will break.
