Abstract
A cutting bit, in particular an indexable cutting bit, has a polygonal base body with a flat bottom side (1), a flat or structured top side (4) spaced apart from the bottom side, and a number of side surfaces (2) adjoining one another, forming corners (3). On the top side, the base body is beveled to descend in the outward direction of the region of the chip removing surface at at least one corner (3), in such a way that at the corner a delimited region (9) is formed that is inclined with respect to the bottom side (1). In this inclined region (9), on one side of the corner (3), the main cutting edge (5a , 5b) extends to the vicinity of the corner (3), while on the other side of the corner in the inclined region a plane, or facing, cutting edge (5c) is formed, which essentially adjoins the main cutting edge, and the portion of the main cutting edge located in the inclined region (9) has essentially at most the same length as the plane cutting edge.
