Circular saw blade

A circular saw blade, comprising a circular body with two side faces and having an outer diameter (D), a central bore with a diameter (K), a peripheral edge provided with a plurality of cutting teeth, said blade body being formed with at least three inner radial slots extended outwardly radially from said central bore and circumferentially spaced from each other and with at least three outer radial slots extended outwardly radially towards said peripheral edge and also spaced circumferentially from each other, said inner radial slots terminating at a circumference having a first diameter (B), said outer radial slots extending between a circumference having a second diameter (A) and a circumference having a third diameter (C) exceeding said first diameter, said inner and outer slots being distributed circumferentially and radially in sets each including one inner slot and one outer slot, the outer slot in each set partially overlapping the inner slot in the same set in a radial direction to define a radial lap (U) therebetween and the outer slot in each set being circumferentially spaced from the inner slot in the same set to define a peripheral distance (V) therebetween, each of said slots having a width of not more than 2 mm substantially along the entire length of the slot, the ratio of the length of said lap to said peripheral distance being greater than 1:1, said third diameter (C) being greater than 0.5 the sum of said outer diameter (D) and the diameter (K) of the central bore.
