Abstract
A tool holder simultaneously carries at least two diametrically arranged tool heads, each tool head carrying cutting inserts for chip removing machining. The tool holder includes an adaptor connected to a coupling. The adaptor has at least two diametrically opposite side surfaces which-diverge away from the coupling. The side surfaces have seats in order to replaceably receive respective tool heads. A line which lies in both a first basal plane and in one of the side surfaces forms an angle in the interval 1°–15° with a longitudinal center line of the tool holder.

A tool holder for simultaneously carrying at least two chip-removing tool heads, comprising:
- a coupling defining an axis of rotation;
- and
- an adapter including axially spaced front and rear ends, the rear end mounted on the coupling to be driven thereby, the adapter including at least one pair of side surfaces arranged generally diametrically opposite one another with respect to the axis and facing away from one another, the pair of side surfaces converging toward an imaginary point of intersection spaced axially rearwardly of the axial front end of the adapter, each of the side surfaces of the pair including a seat configured to replaceably receive a tool head, the pair of surfaces being bisected by an imaginary basal plane, wherein a line lying in both the basal plane and either of the pair of side surfaces forms with the axis an angle of inclination in the range of 1–15 degrees.
An adapter for simultaneously carrying at least two chip-removing tool heads, comprising a body defining a center axis, the body including axially spaced front and rear ends and at least one pair of side surfaces arranged diametrically opposite one another and facing away from one another, the rear end defined by a contact surface including a connection structure adapted to connect to a coupling;
- the pair of side surfaces converging toward an imaginary point of intersection spaced axially rearwardly of the axial front end, each of the side surfaces including a seat configured to replaceably receive a tool head, the pair of surfaces being bisected by an imaginary basal plane, wherein a line lying in both the basal plane and either of the pair of side surfaces forming with the axis an angle of inclination in the range of 1–15 degrees.
