The component (10) has a drilling bit (32) with a drilling section made of metal and a connection section, and an anchor rod (12) made of plastic. The anchor rod is extended along an anchor axle (X), and comprises a connection section (16) for fastening the drilling bit at a region of an axial rod end. Outer dimension of the drilling bit is maximum of 10 percent and/or 10 mm larger than outer dimension (d12A) of the anchor rod at the connection section of the drilling bit. A separate sleeve (54) e.g. steel sleeve, closes the anchor rod at a region of the connection section of the drilling bit. |
