ABSTRACT:
The invention concerns a new type of tool for engraving machines comprising an oblong body (11a) provided at one end of an insert-receiving (19) pocket (18).
Said insert includes a cutting tip end (19a) at one end, one rear surface (23), as well as an intermediate surface in the shape of a cylindrical body (22) truncated by an oblique flat piece (24), the section of said cylindrical body (22) tapering away from said tip end (19).
Said oblong body (11a) is provided with a pocket (18) including a cylidrical wall corresponding to that of the cylindrical body (22), as well as a wall slanted in such a way as to be adapted to the obliquity of the flat piece (24), the surface of said wall (25) exhibiting a convexity in a radial and/or longitudinal direction so that said insert (19) can be inserted and maintained in said oblong body (11a) by jamming the flat piece (24) in the pocket (18).
