The set, from the company Kraft & Dele, consists of tools made of hardened chromium-vanadium steel (Cr-V). Chromium ensures the steel's resistance to corrosion, oxidation, friction, and high temperature strength.

The addition of vanadium inhibits the growth of grains during processing, while increasing the density of both the annealed and hardened forms. A durable plastic case allows you to maintain order and easily transport the tools. Each tool has a designated place where you can easily find the required size of wrench.
