The circular saw blade (1) has several cutting teeth (2) which have a main free face, two axially spaced secondary free faces and a tooth spine (5). The main free face extends in a first section (A1) with a predetermined first free angle, starting from the main cutting edge towards the tooth spine with a main free face active width which is less than the tooth thickness and the first section is adjoined in the direction of the tooth spine by a second section with a width which is stepped relative to the first section and/or has a larger predetermined free angle than same.
