Embodiment Construction

[0028] The incisor 1 shown in the figures has a base body 2 which essentially consists of a flat plate 22 . as in particular by figure 2 and 3 As can be seen in the side view, the base body 2 has an upper edge 31 and a lower base region 28 . In the bottom region 28 of the lower part, the plate 22 of the base body 2 ( Figures 1 to 3 ) are formed with rivet openings 11 and 12 which follow each other in the running direction LR of the cutting tooth 1 . Rivet opening 11 is the preceding front rivet opening and rivet opening 12 is the following rear rivet opening.

[0029] as in figure 2 and 3 As shown in , each rivet opening has center axes M1 and M2 with a rivet distance N from one another in the running direction LR.

[0030] A chip recess 5 is formed in the upper edge 3 of the base body 2 , with a depression 30 in the upper edge 31 ( image 3 ) and the residual flange 34 leading in the direction of travel LR. The residual flange 34 is bent outwardly from the plane of...

Abstract

The invention relates to a cutting tooth (1) for a saw chain, comprising a base body (2) with a base in the body (2) attached to the cutting element (3) made of hard metal. The cutting element (3) made of hard metal has a roof edge (16) and a side portion (7) with a side edge (17). In the base body (2) a cutting recessed part (5) is provided for clamping derivative, wherein the cutting element (3) in the cutting recessed part (5) protrudes, and in side view onto the base body (2) has a front contour (14) of the side portion (7) and the inner contour (15) of the cutting recessed part (5) form a corner (8) . According to the invention, the vertex (8) is located at a first distance (A) to the cutting recessed part (5) defining the high edge (9) of the depth gauge (4) which is smaller than a second distance (B) of the rivet spacing and pitch (N) dividing the central plane (V) to the high edge (9) of the depth gauge (4). The high edge (9) of the depth limiter (4) is in the running direction (LR) in front of the center axis (M1) of the front rivet opening (11).

Description

technical field [0001] The invention relates to a cutting tooth for a saw chain according to the preamble of claim 1 . Background technique [0002] An incisor of this type is known from DE 10 2007 050 778 A1, which comprises a base body with a cutting element made of hard metal fastened to the base body. Rivet openings are formed in the bottom region of the base body, which follow each other in the running direction of the cutting teeth. A depth limiter is arranged on the base body before the cutting element in the direction of travel. A chip recess is formed between the depth limiter and the cutting teeth. The cutting element is held in a depression in the upper edge of the base body, wherein the side sections of the cutting element are fastened to the sides of the base body by means of brazing. Good cutting results are obtained with this known cutting tooth. [0003] The cutting element made of hard metal is designed to be small relative to the base body, so that the ...
