<p>The invention relates to a method for attaching tooth bits to a saw blade body. The mating surface (8) of an attachment point provided in the blade body, transverse to the blade's direction of motion (A), is formed such that it is rearwardly oblique at its outermost part, whereby the blade body (4) may bypass a broken tooth bit fragment (5) without being damaged. A discontinuity point, at which the tooth bit (2) fractures controllably, may also be formed in the tooth bit (2).The invention further relates to an arrangement for attaching the tooth bits (2) to the blade body (4) used in sawing. In the arrangement, the outermost part of the mating surface (8) supporting the tooth bit (2) is formed to be rearwardly oblique and the tooth bit (2) has a given protrusion (10) with respect to the blade body (4), with the result that the blade body (4) may bypass the tooth bit fragment (5) without breakage.</p> |
