CIRCULAR SAW BLADE WITH A GROOVED BODY AND METHOD OF MAKING THE SAME

A method of improving a circular saw blade, the circular saw blade comprising a body having circumferential cutting teeth, the method including grooving the saw blade body, in wherein grooves (4a, 4b; 5a, 5b; 6a, 6b; 7a, 7b; 8a, 8b; 9a, 9b; 10a, 10b; 12a, 12b) on both sides of the body (2) are formed, said grooves having a depth (g) smaller than the thickness (t) of the saw blade body (2) and extending in a direction different from the radial direction of the circular saw blade, and wherein said grooves are comprised in evenly distributed angular grooved sections (I, II, III, IV, VI, VII, VIII) covering at least a part of each surface of the body, in which grooved sections each radial cross-section (A-A) of the body comprises at least two grooves (4a, 4b; 5a, 5b; 6a, 6b; 7a, 7b; 8a, 8b; 9a, 9b; 10a, 10b; 12a, 12b), each of said two grooves being located on a different side of the body, so that each groove (4a, 4b; 5a, 5b; 6a, 6b; 7a, 7b; 8a, 8b; 9a, 9b; 10a, 10b; 12a, 12b) on one side is located in a part of the body (2) that is free of the grooves on the opposite side of the body. A circular saw blade improved by the method according to the invention.
