Why are sandvik drilling tools so awesome?

Because of the material cow!
In 1862, the founder of sandvik and his engineers used Bessemer steelmaking process for the first time to successfully realize mass production of steel. Because of its high quality, Swedish steel soon became a hot commodity. Rock drilling tools were the first tools to actually apply this kind of steel, and sandvik began to supply this kind of products in the 1970s.
Today, sandvik proudly inherits this time-tested tradition, which gives the company a unique manufacturing capability-independent production of special steel for rock drilling rigs.
The company has never stopped its R&D activities, as evidenced by the large number of patents obtained by sandvik for material technology innovation. Metallurgical technology continues to play an important role in modern rock drilling tools.
