The analysis of methods for assessing the drilling tool performance using various methods was performed. The applicability of the methods was assessed. Methods based on periodic comparative tests were examined in detail. The technical level and operational efficiency of the drilling tool is determined by the resource (tool driftage), drilling speed, durability, power supplied to the bottom of the well. The correct choice of a drilling tool is ultimately determined by economic assessments. The specific drilling costs are proposed to be determined taking into account the cost of one machine hour, the sharpening of crowns and the average mechanical drilling speed.
