Abstract: A drill for electronic conductor plates with a cylindrical drill head which is arranged at the front end of a shank, and which in particular has a working diameter of from 0.5 to 1.2 mm. The rear end of the cylindrical drill head is in the direction toward the drill shank followed by a first shank section of a shorter outer diameter. The drill head and the next following first shank section comprise guiding passages for the drilled out material, especially continuous helical grooves in the manner customary with spiral drills. The drill is characterized primarily in that the first shank section adjacent the drill head conically tapers from the rear end of the drill head in the direction toward the rear end of the drill shank.
