Sintered metal bonded segments with an abrasive action, for tools

In sintered metal bonded segments with an abrasive action, containing particles of a hard material, for tools for machining or cutting hard and/or brittle materials with a tool support which accommodates the segments, wherein each of the segments is made of individual segment modules that are variously formed, the improvement comprising:

• the segments constructed from at least one of the segment modules having identical construction and the segment modules manufactured by high-temperature isostatic pressing and the segments constructed from the segment modules containing alternating concentrations of the hard material particles starting at a leading area of a working edge and progressing towards a trailing area of each of the segments in a direction of motion of the segment, and from the segment modules including varying areas having alternating concentrations of the hard materials arranged perpendicularly to the direction of motion of the segment.
