The mounting body (1) of the boring tool, which is of a hub-like configuration, is provided, at locations which are diametrally oppositely disposed with respect to the axis of rotation (D) of the mounting body, with a respective mounting bore (3) with its axis (A) extending radially with respect to the axis of rotation (D), the mounting bore being surrounded by a respective abutment surface (4) extending perpendicularly with respect to the axis (A) of the mounting bore (3). A tool head (5) is provided with a fitting spigot (6) which fits into the mounting bore (3) and which is concentrically surrounded by an annular surface (7) extending perpendicularly with respect to the axis (A) of the fitting spigot. A respective intermediate portion can optionally be fitted between the mounting body (1) and the respective tool head (5), the connecting parts of the intermediate portion corresponding to those of the mounting body (1) and the tool head (5). The tool head (5) can be connected to the mounting body (1) directly or with the interposition of the intermediate portion, by way of clamping devices (8-13). |
