摘要： The invention provides a segment type diamond tool capable of improving cutting rate and reducing the amount of fine debris generated during cutting by properly arranging diamond particles in a cutting segment of the diamond tool. In the invention, the layers of diamond particles are arranged such that cutting grooves formed on a workpiece by trailing layers of diamond particles are arranged between cutting grooves formed thereon by leading layers of diamond particles, respectively, in cutting of the work piece. The cutting segment has high-concentration and low-concentration areas. The high-concentration area shows a concentration higher than an average concentration and the low concentration area shows a concentration lower than the average concentration. Also, at least one low concentration area is formed on the leading and/or trailing section of the cutting segment. The diamond tool of the invention ensures superior cutting rate and reduced amount of fine debris generated during cutting.

摘要： A segment type diamond tool, used for cutting or drilling brittle substances, such as stones, bricks, concrete structures, or asphalt structures, is disclosed. In the diamond tool, the segments are each set with diamonds in a single-layered structure or a multi-layered structure, and are alternately or intermittently arranged on a steel core, different from conventional diamond tools having segments randomly set with diamonds. Such a diamond arrangement of this invention allows the diamonds to more effectively perform their cutting action, and so the diamond tool has an increased cutting rate, in addition to reducing the amount of fine debris generated during a cutting or drilling process to ill-affect worker's health or cause environmental pollution. In the segments each set with diamonds in the single-layered or multi-layered structure, the diamond arrangement is designed such that the diamonds of each trailing segment form grooves on the surface of a brittle substance along the lands between grooves previously formed on the surface of the brittle substance by the diamonds of a leading segment.
