Claim 26:
27. A grinding tool for grinding an engine block, comprising:
a main body including a central coupling region for connecting the main body to a rotary drive of a grinding machine, wherein the main body is of a substantially rotationally symmetrical configuration with respect to an axis of rotation;
a grinding layer which is arranged on the main body and extends at least over an outer circular ring zone of the main body;
at least one feed for a cooling fluid; and
a substantially circular cover plate which is arranged substantially normal to the axis of rotation and forming an axial gap on the main body, wherein the axial gap is in fluid communication with the at least one feed and the grinding layer so that a cooling fluid fed by way of the at least one feed can be passed by way of the axial gap to the grinding layer,
wherein a first surface of the main body and a second surface of the cover plate face each other in opposite axial directions, and first passages for specifically passing the cooling fluid from the at least one feed to the grinding layer are arranged at the first surface of the main body or at the second surface of the cover plate, the first passages being arranged in a plane parallel to the first surface of the main body,
wherein a majority of the grinding layer extends along an axially front surface of the main body,
wherein each of the main body and the cover plate has an inclined surface which is inclined relative to the axis of rotation and which adjoins the grinding layer, and portions of the inclined surfaces are in direct contact with each other, and
wherein second passages are formed by grooves in at least one of the inclined surfaces.
