By aiming at a problem of inability of determining a defective area of a wear-resistant band of a drilling tool in a quantitative way during the detection of the drilling tool, the invention discloses a defective area detection area. The defective area detection device comprises a colorable grid-type area detection band, which is used to wrap the outer periphery of the wear-resistant band tightly. During the detection, the grids of the detection bands of the defective parts of the wear-resistant band are colored, and a number is counted, and then the size of the defective area is determined, and therefore the damaged area of the wear-resistant band of the drilling tool is detected in a quantitative way, a more accurate detection result is provided, and the detection efficiency of the wear-resistant band of the drilling tool is improved.
