ABSTRACT:
A cutting wheel for natural and artificial rock, such as road surfaces of asphalt or concrete, comprises a carrier disk with cutting segments in a regular series around the circumference of the carrier disk. The series is interrupted at spaced intervals, by at least two extra segments which are made of a material harder than that of the cutting segments and are preferably clad with diamond abrasive material. The extra segments are quadrilateral and have their radially inner edge inclined upwardly in the direction of rotation of the cutting wheel. The correspondingly upwardly inclined portion of the cutter wheel provides a base to which the extra segment is soldered. The extra segments have the same width as the cutting segments, which width is greater than the thickness of the body of the cutting wheel.
