摘要： The invention relates to a cutting insert (1) having two opposite cutting heads (2, 2') in relation to the longitudinal axis (A). The cutting heads (2, 2') respectively comprise a cutting edge (3) which extends essentially in a perpendicular manner in relation to the longitudinal axis (A) and two lateral cutting edges or cutting edge sections (4) which extend essentially in the direction of the longitudinal axis (A) of the cutting insert (1). The lateral cutting edges (4) are inclined downwards from the front side of the cutting edge (3) in relation to the tool reference level Pr. The free surfaces (5) of the lateral cutting edges (4) of the opposite cutting heads (2, 2') which are located on the same side of the cutting insert (1), are arranged respectively on a common plane E. As a result, the lateral edges (4) can be grinded more economically.
