Executive body of a miner comprises a housing in which the cutter blocks are installed, those contain a cutter holder with a through cylindrical bore in which a sleeve made of wear-resistant material is placed the cutter tool shank inside it. To improve the efficiency of the executive body, the cutter blocks are adapted to quick replacement of radial cutters on tangent and vice versa - by performing the shanks of tangent and radial cutters in cylindrical form and with the same diameters, at that each cutter block is equipped with means for preventing rotation of the radial cutters around the longitudinal axis, this provides installation in cutter tool holders of one executive body of interchangeable tangential and / or radial cutters, depending on mining-geological conditions and the destructed rock mass parameters.
