The work is devoted to the results of production tests of a multilayer diamond crown with a comb profile of all impregnated layers separated by diamond-free layers of lower hardness. A distinctive feature of the crown is the placement of diamond-containing layers on a three-way screw surface with a small step. This makes it possible to involve in the process of deepening the fungus into a partially cracked zone the rock lying under the zone of diamond grains introduction. The zone of theoretical justification of the effectiveness of the profile of the matrix. The above-mentioned patent crown under the abbreviation KSB-3M (HQ) has passed production tests at the helogical facility of the Kazakh company. Rocks are mainly represented by carbonaceous-siliceous metagalium of the XIII - IX and partial X-th category. Drilling was carried out with the use of projectile with removable core receiver. 389 wells were drilled with one experimental crown, and most of the footage falls on the IX–category rock, which indicates the great durability of the tool. The mechanical drilling speed varies from 5.5 to 3.5 m/h depending on the rock quality. It was decided to continue experiments with KSB-3M crowns on other geological sections with harder rocks.
