Saw tooth holder, cutting disk for a rotarty cutting machine and rotary cutting machine including same

A saw tooth holder for a cutting disk of a rotary cutting machine, the saw tooth holder comprising:

• a holder body having a tooth-receiving surface abuttable against a rear surface of a saw tooth of a tooth assembly and a trailing surface, opposed to the tooth-receiving surface, and defining a trailing oblique angle with respect to the tooth-receiving surface,
• the holder body having a fastener-receiving aperture extending therethrough between the tooth-receiving surface and the trailing surface and being accessible from the tooth-receiving surface and the trailing surface,
• wherein the trailing oblique angle is comprised between about 30 degrees and about 60 degrees, and
• wherein the fastener-receiving aperture extends along a fastener axis substantially perpendicular to the tooth-receiving surface and includes a front portion extending rearwardly from the tooth-receiving surface, the saw tooth holder further comprising a fastener-receiving socket defined therein and extending forwardly from the trailing surface and surrounding the fastener-receiving aperture and defining a fastener-abutment surface in the holder body, the fastener-abutment surface at least partially delimiting inwardly the fastener-receiving socket and extending substantially parallel to the tooth-receiving surface.
