Abstract
A variable-tooth circular saw blade (1) with cutting teeth (3) in a plurality of circumferential groups has the successive teeth (5-8) in each group first reducing and then increasing in pitch. This gives the blade an improved combination of cut, reduction of noise and vibration, together with higher speed. <IMAGE>
