摘要

Improvements in the construction of chiseling tools, characterized in that the active zone of the same, destined to the pertinent actions, by means of contribution of movements to the effect, consists, on the one hand, of three cutting edges arranged radially on the front frontal face, suitable for working in the direction of longitudinal penetration, and, on the other hand, of so many axially disposed edges, in combination with those, suitable for working laterally when the tool is moved in this direction, so that the action of the latter is produced indistinctly, at will, in the radial direction of penetration and in the translational axial, all in order to obtain laterally elongated holes in the same operation, said edges presenting a helical structure in the sense that the Attack of the body to be tilled is initiated by the part of the axial edges corresponding to the base of the active zone of the h tool, so that each point of the leading edge is in phase shift with respect to the immediate points, and so, according to what has just been stipulated, each point of the said edge is in advance in relation to the following points, considering the order of succession of such points from the back to the front of the tool.
