Abstract

Three or more drums (3) with helical profiles (4) at their outer surfaces are joined to a cylindrical tool head (12). The diameter of the tool head (12) is smaller than the diameter of the combined drum unit (3) but bigger than the diameter of the shaft (2). When the head (12) is activated each of the drums (3) starts rotating around its individual axle in the opposite direction to the main rotation and moved only by the contact to the bore to be provided with an inner thread.
