Amber drilling machines
Drill machines for beads, amber balls and pearls. When making beads of elements having an elongated shape, the difficulty is the drilling of longitudinal holes. The work can be made easier by drilling in three stages: at first, a thin drill is drilled 60% of the length on one side, then by the same drill, on the other hand, to the through hole, after which the hole is drilled to the desired size.
