Abstract: In an annular saw, that is to say a circular saw with an annular saw blade, the saw blade is adapted to rotate about an imaginary center axis by being driven via a drive shaft which is parallel to the center axis and has a fulcrum between the annular saw blade and its center. Mounted on the drive shaft (27) are two drive rollers (25, 26), of which the adjacent surfaces (41, 42) are bevelled at a certain bevel angle so that the rollers comprise drive surfaces which, between them, form a wedge-shaped groove (40). The two lateral surfaces of the saw blade (8) are bevelled in a corresponding manner within a region (13) close to the inner edge (15) of the saw blade, the bevel angle being the same as for the drive rollers, the bevelled edge portion of the annular saw blade being clamped between the bevelled drive surfaces of the drive rollers in the wedge-shaped groove.
