The invention discloses a method for measuring the depth of a superhard abrasive impact toughness sample tube. By cleaning a sample tube with alcohol before measurement, the influence on the measurement result caused by dust and sundries adhered to the sample tube can be effectively avoided, the measurement error is reduced, and the measurement accuracy is improved; and a G5-precision steel ball with high ball precision is adopted, the steel ball diameter and the measurement direction are independent from the direction of putting the steel ball into the sample tube effectively, thus the measurement is more convenient, accurate and effective, and the repeatability measurement error can be effectively controlled below 0.01mm. In the measurement method disclosed by the invention, the tool selection is easy, and the measurement steps are simple and convenient; more importantly, the measurement result error is low, the data is accurate, the error is low, thus the performance index and product grading of the superh
