Tool for machining a workpiece

A tool configured to machine a workpiece, comprising:

• a cutting head having a sleeve and a cutting element, wherein the cutting element is fixed to the sleeve and comprises at least one cutting edge, and wherein the cutting head extends along a first longitudinal axis;
• and
• a holder to which the cutting head can be detachably fixed, wherein the holder extends along a second longitudinal axis;
• wherein the sleeve comprises a first axial bearing surface which is an annular surface that at least partially surrounds the first longitudinal axis and runs orthogonally to the first longitudinal axis, wherein the sleeve comprises a first conical bearing surface which at least partially surrounds the first longitudinal axis and runs symmetrically to the first longitudinal axis, and wherein an internal thread is arranged in a first region inside the sleeve, said region extending along the first longitudinal axis between the first axial bearing surface and the first conical bearing surface,
• wherein the holder comprises a second axial bearing surface which is an annular surface that at least partially surrounds the second longitudinal axis and runs orthogonally to the second longitudinal axis, wherein the holder comprises a second conical bearing surface which at least partially surrounds the second longitudinal axis and runs symmetrically to the second longitudinal axis, and wherein an external thread is a straight thread and is arranged in a second region on the holder, said second region being cylindrical and extending along the second longitudinal axis between the second axial bearing surface and the second conical bearing surface, and
• wherein, in an assembled state of the tool, the internal thread is screwed to the external thread, the first longitudinal axis coincides with the second longitudinal axis, the first axial bearing surface bears against the second axial bearing surface and the first conical bearing surface bears against the second conical bearing surface,
• wherein the first conical bearing surface is inclined at a first inclination angle relative to the first longitudinal axis, and wherein the second conical bearing surface is inclined at a second inclination angle relative to the second longitudinal axis, wherein the first and the second inclination angle are equal,
• wherein 100≤α1=α2≤450, wherein α1 indicates the first inclination angle, and α2 indicates the second inclination angle.
