Cutting element and the use thereof

A cutting element being configured for machining a non-metallic composite material composed of a matrix and particles held together by the matrix, the cutting element comprising:

• a flank face;
• a rake face;
• and
• a cutting edge being coated by an edge coating and via said cutting edge, said flank face and said rake face are connected to one another, said cutting edge within a cutting edge section thereof is curved such that said cutting edge immediately beneath said edge coating in a section in a section plane that is perpendicular to said cutting edge has, at every point of said cutting edge section, a local radius of curvature which is greater than or equal to 10 μm and less than or equal to 80 μm;
• said cutting edge formed from a cemented carbide at least in a region of said cutting edge section;
• said cemented carbide having hard material particles forming a skeletal structure of said cemented carbide;
• and
• said hard material particles having a grain size in a range from 0.1 μm to 1.5 μm.
