PURPOSE: An abrasion wheel is provided to prevent the deviation of tips due to the carbonization or oxidation of abrasives such as diamond in response to the increase of thermal impact applied to the abrasives by reducing the frictional heat by slantly forming air suction holes. CONSTITUTION: An abrasion wheel includes a core part(11) having a mounting hole(H) in the center for mounting an output end of an electromotive element, and long tips(21) and short tips(22) alternately and radially mounted on a bottom surface of a shank(11) at a periphery of the core part by a uniform interval, wherein the respective long and short tips are formed with an area becoming wider outwardly in the radial direction, and suction holes(23) are penetratingly formed in front of the short tips between the long and short tips.
