ABSTRACT:
A saw blade having a basic body (1) and unset teeth (2.sub.1, 2.sub.2, etc.) having recurring cycles of teeth, each cycle having at least one group of teeth with at least three teeth, and where tooth height decreases from tooth to tooth while tooth width simultaneously increases. The teeth (2.sub.1, 2.sub.2, etc.) are formed symmetrically with respect to a longitudinal center plane (8) extending through the basic body (1). The effective cutting edges or cutting-edge sections (6.sub.1, 12.sub.1, 14.sub.2, 12.sub.2, etc.) of each tooth (2.sub.1, 2.sub.2, etc.) are formed by a jutting-out or protruding cutting edge, the inner section (6.sub.1, 6.sub.2, etc.) of which runs approximately perpendicularly with respect to the longitudinal center plane (8) and which is adjoined externally by a phase (7.sub.1, 7.sub.2, etc.) inclined toward the basic body (1) The widest tooth (2) in the group of teeth has an angle greater than 90 degrees formed between phase (7 ) and flank (10).
