Tuning for drilling, sinking and cutting RUKO‘s own coating Best of the best: Our RUnaTEC coating impresses with absolute top values. In the areas of friction loss, nano-hardness, the ability to work at extremely high cutting speeds up to a maximum of 1,100 degrees Celcius and a tool life that is up to 16 times longer than uncoated cutting tools. Coated tools may be recognizable at first glance, but they are far more than just cosmetics. This is because, as in motor racing, the aim of coatings is to maximize the performance and durability of each tool. This includes, for example, a significant...
