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.

摘要： A diamond blade having rim type cutting tip for use in apparatus such as cutting saw machine having a structure which rim type cutting tip is able to produce cutting chips with relative large size during cutting operation so that those chips are easily discharged outside with reducing the friction with cutting tip of blade, thereby to increase cutting ability and to prevent the chips dispersing in the air and giving rise to the bad effects to user's health and the contamination of environment. The diamond blade according to the present invention comprises a wheel body connected with a shaft of electric motor, and rim type cutting tip for cutting or grinding crushable materials disposed on the circumference of the wheel body and composed of at least two diamond layers longitudinally disposed parallel with the rotation direction of the blade in which diamond particles are included, and non-diamond portion disposed between the diamond layers in which diamond particles are not included.

摘要： The present invention relates to a saw blade for preventing undercut wherein out of the sludge discharging slots arranged together with undercutting segments and ordinary cutting segments on the circumference of a steel wheel, those slots located behind the undercutting segments are dimensioned larger or wider than the slots behind the ordinary cutting segments in order to prevent the breakage and falling-off of the undercut preventing segments and ordinary cutting segments. Thus, according to the invention, there is provided a saw blade including a steel wheel, and on the circumference of said steel wheel, plural ordinary cutting segments and undercut preventing segments, two or more segments of one type being arranged alternately with one or more segments of the other type, characterized in that at the rear faces of respective ordinary cutting segments narrow slots with a predetermined narrow clearance n are formed for minor discharge of cut sludge and at the rear faces of respective undercut preventing segments wide slots with a larger clearance w than the narrow slots are formed for major discharge of cut sludge, the directions being based on the rotation of the blade wheel.
