Abstract: A stone saw blade (1) includes an elongated base body (2) and a plurality of teeth (3). The teeth (3) are designed and arranged to be unset and to include geometrically defined cutting portions (11). The teeth (3) include a form body (4) being connected to the base body (2). The form body (4) includes a carrier (21) being made of hard metal and a layer (5) forming the cutting portion (11). The layer (5) has a hardness of at least 5,000 HK.

Abstract: A saw blade (1) includes a base body (2) and a plurality of teeth (3). The base body (2) defines a longitudinal center plane (14). The teeth (3) are designed and arranged to be unset and to be symmetric with respect to the longitudinal center plane (14). The teeth (3) are designed and arranged to form at least one group of teeth (3) on the base body (2). The at least one group of teeth (3) is repeated on the base body (2). The group of teeth (3) includes at least a first tooth (31) and a second tooth (32). The first tooth (31) includes a first cutting edge (101) being designed and arranged such that at least a portion of the first cutting edge (101) is designed to be rounded and to have at least one first radius (181). The second tooth (32) includes a second cutting edge (102) being designed and arranged such that at least a portion of the second cutting edge (102) is designed to be rounded and to have at least one second radius (182). The second radius (182) is different than the first radius (181).

Abstract: The saw blade (1) includes an elongated body (2) having a longitudinal edge and defining a plane of main extension (6). A plurality of protrusions (4) each is located in the region of the longitudinal edge and each includes a seat (12). A plurality of form bodies (5) each is made of hard cutting material, has a cross section (15) and is connected to one of the seats (12). Each cross section (15) of the form bodies (5) in the plane of main extension (6) at a side facing the respective seat (5) is limited by a line (16) in the form of a circular arc, and at a side facing away from the respective seat (5) it is limited by a front line (17) of a surface (18). The line (16) in the form of a circular arc and the front line (17) enclose a wedge angle (22) which is less than approximately 90 degrees, and they are designed and arranged to form a free angle (23). A plurality of cutting portions (10) each extends approximately transverse with respect to the plane of main extension (6).

Abstract: A saw blade comprising a basic body (8) lying in a longitudinal center plane (9) and having an edge and including along its edge a group (6) of recurring teeth (1, 2, 3, . . . ), the group (6) comprising at least one unset leading tooth (1) being provided with a phase and having an effective cutting-edge section (10) and a preferably even number of trailing teeth (2, 3, . . . ). The leading tooth (1) has a larger height than all of the trailing teeth (2, 3, . . . ). All of the trailing teeth (2, 3, . . . ) have different plastic deformations at their tips (28) by displacements of material in the running direction (24) of the saw blade. Each of the trailing teeth (2, 3, . . . ) have both a positive enlarged rake angle (gamma.sub.2, gamma.sub.3, . . . ) and a reduced height (h.sub.2, h.sub.3, . . . ) with respect to the leading tooth (1) produced by different plastic deformations.
