<p>Saw blade, especially a circular saw blade, with replaceable tips wedged in recesses along the periphery of the blade, and held there by elastic forces. Inwards of each recess, but not connected with the recess, at least one tension distributing hole is provided. The contour of the blade body runs inwards from a line between the edges of the tips so far that the bottom of the contour lies farther from the line between the tips than the outer portion of the tension distributing holes, but closer to that line between the tips than the inner portion of said holes. With this arrangement the elastic wedging forces produce tangential tension stresses and only local compressive stresses.</p> |
