The invention relates to a sawing tool comprising a substantially disk-shaped support (1) from which a plurality of tooth inserts (4) project which are juxtaposed along a supporting edge (3) and have at least one sawtooth (12) each with at least one tooth rear (12) and at least one blade (9). The tooth inserts (4) are connected to the support (1) in a position-stable manner even when the sawing tool is operated. The supporting edge (3), in its cross-section perpendicular to the plane of the disk, has a rooflike shape and the tooth inserts (4) have a mounting (8) configured as a rooflike recess mating the roof shape of the supporting edge (3). Recesses (13) and/or bulges are arranged along the supporting edge (3) and are associated with corresponding bulges (14) and/or recesses on the interior of the mounting (8) of a tooth insert (4) and the bulges (14) fit into the corresponding recesses (13) in a form-fit manner.
Sawing means comprising a substantially disc-shaped carrier (1), from which there protrude a plurality of tooth inserts (4) which are arranged next to one another along a carrier edge (3) and which have in each case at least one saw tooth (12) with at least one tooth back (12) and at least one cutting edge (9), wherein the tooth inserts (4) are connected to the carrier (1) in a positionally stable manner even during sawing operation, characterised in that the carrier edge (3) is triangular shaped in a cross-section transverse to the disc plane, and the tooth inserts (4) have a mount (8) configured as a triangular shaped cutout and the cutout has a longitudinal dimension in the sawing direction (S) and a triangular cross-section perpendicular thereto and the cutout matches the triangular shape of the carrier edge (3), and cutouts (13) are provided which are arranged along the carrier edge (3) and to which there are assigned corresponding bulges (14) arranged on the inside of the mount (8) of a tooth insert (4), and the bulges (14) protrude in the center of the triangular shaped cutout directed towards the carrier (1) and the bulges (14) fit into the corresponding cutouts (13) with a form fit.
