(57) The invention relates to a cutting tool, in particular a diamond-tipped cutting tool
for cutting stone materials, formed by a sheet steel support core (1) with a plurality
of cutting elements (2), such as highly abrasive diamond segments which are fixed
at intervals along its cutting edge. In order to achieve sound-damping of said tool,
a series of substantially parallel incisions (3), arranged inclined with respect to
the cutting edge at an angle of 20° to 40° is formed in a central zone of said sheet
metal support core, the ends of each incision, which are formed in the manner of a
curl (3a), being located above the ends of the incisions adjacent thereto. Moreover,
filling segments (5) are arranged between the diamond segments, said filling segments
being fixed to the bottom edge of the blades in a manner similar to the said diamond
segments, with the function of increasing the bearing contact area of the blades inside
the cutting groove. The invention also relates to a frame-type cutting machine, the
blade-carrying group of which has, associated with it, damping means suitable for
preventing the generation and/or the propagation of acoustic vibrations, such as calibrated
spacer strips and/or damping blocks which are made of resilient sound-absorbing material
and arranged between each pair of blades and/or between the latter and the frame.
