Abstract
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.

The analysis of methods for assessing the drilling tool performance using various methods was performed
The technical level and operational efficiency of the drilling tool is determined by the resource, drilling speed, durability, power supplied to the bottom of the well
With a difference in the methods for assessing the operability and efficiency of the drilling tool, all of them, with proper practical application, contribute to improving the technical and economic performance of mining enterprises, including increase of labor productivity, production profitability by reducing drilling costs
Summary
The analysis of methods for assessing the drilling tool performance using various methods was performed. To assess the operability and performance of the drilling tool in a particular enterprise, various methods of comparative pilot industrial testing of the drilling tool are proposed.
