PURPOSE: To prevent the steel from bending or prevent diamond tips from separating from the steel and expensive diamond does not remain on the outer circumference of the circular steel after using the diamond cutting wheel to reduce economic loss thereof. CONSTITUTION: In a diamond cutting wheel for cutting a difficult-to-cut material such as stone, concrete, asphalt and tile by adhering diamond tips to the outer circumference of a circular steel on a central part of which central shaft hole(40) is formed, and which is a disk type rotary body, the diamond cutting wheel is characterized in that the diamond tips are formed in such a way that prominence and depression parts(30) formed in an uneven shape from the outer circumference of the steel to an inner part of the steel are arranged on an inner part of shank(20) with being spaced apart from each other, a bump part(60) is formed on an end of the prominence and depression parts, the prominence and depression parts are formed in such a manner that the prominence and depression parts are not deviated from the outer side of the outer circumference of the shank, and slots(50) are formed on the outer circumference of the shank with being arranged in a certain distance, wherein the bump part is not formed on the end of the prominence and depression parts, but the diamond tips are adhered to the inner side of the prominence and depression parts. |
