A boring tool, in particular a borer, has disposable cutting bodies that form the cutting edges, and chip-removing grooves. A chip forming area (22) at least partially made of a more wear-resistant material than the borer body itself is arranged next to the faces (11) of the main cutting edges (5) approximately in the chip flow direction. In another embodiment, the chip forming area if made of the same material as the borer body and is subjected to a subsequent local hardening process that makes it wear-resistant. |
