Set of 12-piece curved spanners 6-32 KINZO Holland Pros. Kyiv

I brought two sets from Holland a few years ago, one is used by this day (my workshop, but not a single key broke or slipped.) Took 100 euros for each set. The quality is super, professional.
Size line: 6x7; 8x9; 10x11; 12x13; 14x15; 16x17; 18x19; 20x22; 21x23; 24x27; 25x28; 30x32 mm.
The annular structure of the working part allows to evenly distribute the load at the moment of application of the force, which significantly reduces the risk of "slipping" of the edge of the corner. Reliability and durability of the tool is ensured by the material used to make the keys — chrome-vanadium steel. This causes very high operational characteristics: increased resistance to mechanical loads, corrosion resistance and hardness. In addition, this alloyed steel has a favorable modulus of elasticity, and the convenient shape of the key and a special bend provide optimal conditions for the application of force even in those places where an ordinary socket wrench would be useless.
