Plagiarius Prize: The brazen plagiarism of the year

With a step drill you can drill different sizes without changing the drill. According to the jury, the German tool manufacturer Karnasch is said to have taken over all the innovative product features of the original (left) from Ruko GmbH from Holzgerlingen. This includes the number of drilling steps, the diameter and the height of the individual steps, the cutting geometry, the center point and also the radii at the step transitions. The patent granting process from Ruko is still ongoing, Karnasch denies the novelty and argues that the "state of the art" can be freely used.
