Circular saw blade

Abstract

A circular gang edger blade comprises a plurality of teeth having a cutting angle and being arranged on the periphery of the blade so as to yield a pitch between two adjacent of the teeth between about 2.3 cm and about 3.2 cm; each pair of adjacent teeth defining a rounded gullet therebetween for receiving and removing sawdust. The teeth are configured and sized so that each gullet defines a sawdust-receiving area comprised between about 1.1 cm2 and about 1.7 cm2. Some of the gullets are provided with a recess defining an expansion joint extending in a direction defining a smaller angle than the cutting angle. Contrarily to gang edger blades from the prior art which are characterized by a sawing variation of at least 0.635 cm, it has been observed that a gang edger blade according to the present invention is characterized by sawing variation of no more than 0.25 cm.
