diamond tool cutting segment and diamond tool with segment

摘要

The present invention relates to a cutting segment of a diamond tool for cutting or drilling a brittle work such as stone, bricks, concrete and asphalt, and a diamond tool provided therewith. The invention allows for higher cutting speed and extended service life without suffering r wear during the cutting action. In the cutting segment, a number of diamond particles are distributed in a plurality of platiform layers stacked perpendicular to a cutting direction. each of the diamond particle layers has a plurality of particle rows on a cutting surface. moreover, at least two of the diamond particle layers are superimposed on at least one side of the cutting segment viewed from the front of the cutting segment in the cutting direction. The invention ensures uniform cutting action by significantly reducing wear and tear during the cutting action and thus allows for higher cutting speed and longer service life.
